    Great fitness watch, looking forward to updates

    Purchased this watch for mainly tracking activity during the day and also treadmill and exercise bike workouts. First off the activity tracker works very well and motivates me to keep active. The alert for inactivity is helpful but wish it had a vibrate in addition to a tone for this. In terms of tracking workouts that don't involve the GPS a heart rate monitor is mandatory to log these properly and the M400 with heart rate strap fits the bill for this. For this the watch works very well, it logs my exercise bike workouts very well in terms of heart rate, time on the bike and calories burned. However to put the distance in you need to this from the website, there is no ability to do this from the watch or from the Android app. In terms of treadmill work it is the same as the exercise bike in terms of what it tracks, when you enter workout mode it does not track steps with the built in pedometer and tie those to the workout. Overall I am very happy with this watch but look forward to some firmware updates soon. Pros: Heart rate monitor is top notch. The ability to track workouts with the heart rate monitor and see those on the website and mobile app. Combines a lot of functionality into one device, it allow me to use one device to track everything. Before I was using my phone to track my workout and then sharing that data with mulitple apps to get the info I needed for me. Progess tracking is very nice on the mobile app and website. Cons: Website and mobile app need some work in terms of more user friendliness. Please add the ability to manually import workouts, edit the workout from the mobile app in terms of editing the distance of the exercise bike ride and somehow track steps on a treadmill and tie that distance to the workout instead of having to purchase a foot pod. Wish it had a vibration alert for inactivity, I have a hard time hearing the beep in a noisy environment. Despite the cons I feel this is one of the best fitness trackers on the market right now and would recommend it. I haven't even had a chance to try the GPS because of the weather but look forward to it.

    Great hybrid activity tracker / fitness watch

    Tracks daily movement with extra advantage of capturing GPS/HR fitness workouts beyond cardio including strength training and yoga. Connects to Polar Flow website and mobile app which are very nice graphical summaries of your daily goals and progress. I bought it as a weight loss companion and have been pleasantly surprised how easy to use, and customizable the workout displays are. You can create a dashboard of conceivably any data you want to look at while working out. So far I have found it very easy to connect to some of my preferred 3rd party apps like myfitnesspal and training peaks. Finally a device that uses a common usb cord (Kindle/Galaxy micro usb) for syncing and charging (does sync to mobile via bluetooth as well). My only complaint is that it does not yet have tools to track treadmill distance - accelerometer doesn't track distance and currently it doesn't seem to support a footpod. I love Garmin products as well, but the Bluetooth connectivity of the Heart Rate monitor by Polar seems to be more universally compatible with the fitness machines I encounter traveling at hotels around the US which is nice. I did have an initial support issue with the HR strap and will say Polar rectified it immediately which was nice. Some final comments on the GPS, GPS accuracy seems to mirror my Garmin Forerunner. Though my workouts tend to be in open sky areas, of the few times I have tried it in a downtown big building environment or dense forest canopy I did have one workout that reported some erroneous distance and mapping, most are fine though.

    Great entry sport watch

    I was looking for a sports watch with GPS, looked at the Garmin site and they were good but pricy and had a lot of functions that I don't really need or want and the ones with a reasonable price lacked the things I fund on this watch. I just love that it keeps track of my activity the whole day even when i sleep without having to put it on sleep mode, also some how it knows the difference when am sitting down or lying down and the difference between laying down and sleeping. So far no problems with the connection to the phone or synching with the, in my case Mac. It takes like 10 seconds to find GPS and once it funded it has never dropped (so far). I tried with my bike and the reading is almost as accurate as my old fashion wireless cat eye bike computer. I do wish it had a color LCD display and an icon for the battery percentage, it only has a battery icon so I have to guess and charge it when I see that it's almost empty ( the icon) aparently it would tell you if the battery is too low for the watch to be used in a work out, that has not happened to me because I try to charged as soon as I see that little icon getting too low. I usually use it on watch mode 5 days with its nights plus 3 to 4 hours on GPS mode without the need of charging so I think the battery life is quite good, I think overal is a good GPS watch for novices like me that only need to know their work out data, if you are looking for something that would tell you what your smartphone is already telling you then this is not for you. I would say check out the polar web site, get all the info you want and then buy it at Best Buy, is cheaper plus you get reward points.

    Great as long as you understand the limitations

    Overall I think this is an awesome watch to track running/workouts with lots of features and customization options as long as you can look at bluetooth/smartphone notifications as more of a bonus that doesn't always work. What I love: - Accurately tracks GPS, distance/elevation, pace and time while running. It's so much easier than relying on the phone for this. - What you see during your workout is highly customizable via the desktop/web interface as you can set up different types of workout profiles and pick what stats are displayed for each type of workout. - You can also use this interface to set up automatic upload to other services like Strava - that way you just need to sync the watch to your phone via bluetooth after your workout, which updates the Polar account, which then updates these services and it is all pretty instant. Limitations: - No vibration. The beeping is loud enough while running but I often miss smartphone notifications during the day that pop up on the watch. - Bluetooth connection can be spotty. May just be my phone (Moto X) but often the phone/watch connection is lost and I need to open my phone's BT settings screen at which point connection is restored. No problem with syncing once reconnected though. - Auto pause stops everything. If you use the auto pause setting to stop the timer when you stop, it pauses everything and you can't do much. That means you can't time your breaks at the track for example. Other observations: - On a full charge there is more than enough battery to last a full marathon with GPS tracking. - HR monitor works well with included chest strap. Some people prefer the ease of a wrist monitor but I have always used chest strap and you get used to it. I think this is a more reliable way of measuring than the wrist monitor as well.

    Great Unit!

    I had an older Polar watch and was quite happy with it. After working on cars, etc, I did scratch up the face pretty good and was a bit difficult to read the display, but didn't really want another watch. To my surprise, my wife bought me this new Polar unit. Yea, it looked nice and all but I thought it was too fancy...but I'll try it out. This thing is way better than I thought! The display is so easy to see now and being able to set up the screens the way I want it, is awesome! very easy to get set up on the computer and then you can download it to the watch via bluetooth. I have the Polar App on my phone and when I open it up, it prompts me to sync with watch. I just push the back button on the watch and away it goes....all synced to the phone. Then the phone pushes to the website automatically, where you can then review your activities more in depth. Very pleasantly surprise how much I like this watch. It also monitors my movements throughout the day and keeps track of calories I've burned walking around the office or just sitting at work. Prompts me if I need to get up and move around too. I'm sure it's more accurate if I wore the HR strap, but it does work without it too (just no the HR stuff). The only drawback is the size. It is a little big on the wrist but I've grown to it and not as bulky as I once thought. Definitely a great unit and a great bang for the buck! Exceeded my expectations! Also, I thought it would sync with my old HR strap, but no go. It needs the newer "bluetooth" one so be sure to get the package if you have an older Polar.

    This product is awesome for what I use it for. The app is ok, but the other function on the watch are awesome. I bought it with the heart strap. The heart strap is comfortable to my standards. Compare to the wrist heart monitor, the H7 is more accurate. The watches with the built-in heart monitor are accurate after you have worked out or ran a few miles. The H7 on certain elliptical or treadmill machine will read the H7 heart monitor and display your heart rate on the machine. As I do cardio, I like to keep my heart rate at the workout rage where it burns the most calories. It is a great product for the price. It is water resistance not waterproof unlike its little brother A300. It can connect to your phone to notify you when there is an e-mail or a text. It all depends on what you are using it for. If it for running, I would say yes come and get it. cardio, CrossFit, body pump to view your heart rate to get the most calories burn. come down and get. If you like to cycle, it has the function as well. It will clock your speed, distance, heartrate and once connect to your phone or computer. It will show you your stats, the route you took. You can also do challenges that are on the polar site and sync it to your watch. It is a great item for me. It works great for what I use it for. I would offer this to my friends, family and strangers. Again, it depends on what type of activity you do. You may not need all the functions. You can find a model below it that fit your needs which is cheaper. It all depends on what you do. Happy exercising.

    Looking for in the middle between beginner and pro

    I am a fitness professional and my interest in tracking my personal progress is beyond what you find in entry level activity trackers; but, does not meet the need of what a professional athlete might want to monitor. This watch is perfect! It tracks daily activity information and alerts me when I need to move. Additionally, when I want more details from of my workout I turn on the GPS and attach the chest strap monitor to record heart rate, speed zones and elevation changes. It is also programmed with a fitness test that measures your VO2 max which helps fine tune into the details if your working out hard enough or not. The reason why I chose this model is that I find having the heart rate monitor on my wrist distracting, of course I want to know my heart rate, but the health of my resting rate is dependent upon my fit rate and it is more important to get accurate information during a workout... and wrist technology doesn't beat the accuracy of chest technology as of this review. The fact that Polar bundles the chest strap with the watch, really gives you the best of both worlds. Side note: They did just release the M 600 but I haven't checked that out 'cause I am VERY satisfied with my M400.

    Great for Multi-Sport, Useful Data

    I have tried and gone through several heart rate monitors in the last 4 years. In the end, none were reliable or useful. Now I have the M400 by Polar, and I am quite impressed with the watch. It appears to be more rugged than the others, and I really like the variety of information it gives about my various workouts. I like the lap timer feature, which is perfect for workouts where I do a set, then am supposed to rest for the same amount of time before doing the next set. It is great for bike riding. The very best feature in my opinion is that the display is large and bright. With past watches, whenever I pressed the backlight button, I still needed a light nearby to see what was on the display. Not so with this one. I can easily read the display under any lighting conditions. And when I press backlight, I am pleased to easily read the data with no effort. As a bonus, the watch doubles as an activity tracker. Highly recommended. Worth the price.

    High Accuracy Tracker, with Bonus Smartwatch

    Make no mistake, some people are not interested in monitoring their workout intensity with this level of accuracy. For those who do however, it's everything you need. The chest strap is comfortable, easily adjustable and very lightweight. The watch itself is also a nice kit. It is easy to read and battery life so far has been convenient. Unless you are running a full day race, it is unlikely you could run it dry if you had no reminder to charge before starting. With my use notifications all the time, HR tracking every other day and GPS tracking 2 times a week, I've only charged it twice since I got it over a month ago. The app is good enough, very straightforward, and has no issues syncing so far (even when the watch claims to fail, it all get's transferred). The occasional freeze on my low-end phone is the only quibble. Where the device truly shines is the addition of smartwatch features. Want turn-by-turn on your bike ride while keeping your phone tucked away? Or notification of who is calling, etc? It's just enough to let you keep it tucked away without missing out on urgent alerts.

    PE & Health teacher perspective = Great product

    I love my polar m400! I will say I am a PE and health teacher and I have always trusted and loved Polar products. For the amount I spent I am definitely satisfied. It keeps track of everything I need it to (calories, pace, HR, and percentage completed of my daily activity goal). I was skeptical at first about how it would be to sleep with it on but I don't even realize that it's on anymore. Also, it looks bulkier in the picture then what it actually as and feels like, in my opinion. I will say I do take it off when I shower but that is just personal preference not actually out of requirement or necessity. It was pretty easy to get set up but sometimes the updates take a bit to get loaded on to the watch (because it has to be done using a Polar program on my computer). It usually takes about 10-15 minutes, from plugging in the device to the end when the device is fully updated.

    This is a replacement for BodyMedia device i had before. Since Jawbone bought them out, I have had nothing but problems getting any help or accessories for my "bugg". So I went on a hunt to find a device similar to what I had before. Lo and behold, I find this little gem. I am ABSOLUTELY satisfied with My Polar M400. I bought it with the HRM strap. Some are sold without the HRM, so if you are looking for both, make sure you chose the right one. It has everything I need in a tracker. I have not had any issues with glitches or anything of the sort. It was easy to set up and it has a free app that you can download and keep up with your progress ( I was paying $9/mo with my BodyMedia device). I would most definitely recommend this to anyone that is serious about tracking their calories burned and overall activies.

    Slightly Hard To Understand Stats

    Posted
    DJyoSNOW

    I do like the M400 w/H7 heart strap! I don't understand goals which should not be based off a question or hours. I saw I was at 147% of my goal, though out of what? It should be by distance or user set. I've noticed a few times my heart rate was 194 and also dropped out, for a minimal tracking time. Also after working out one hour plus, two hours later when resting it will ask me to become active, which I find odd. You can’t track activity in flight mode, I was indoors at work without the chest strap, so what? I honestly feel the chest strap holds me back as I may need to tighten it. I must worry too much that it is going to slip off at any given time. Battery Life is seeming great. App works as intended. There are just a few things that should be tweaked, as stated above. I do find I'm working out more and can track and log my stats. Maybe I’m too picky in hopes Polar will fix some basic features.

    I purchased this over a comparable Garmin Forerunner due to price and features. I've always liked Polar's HR monitoring and since this was coupled with the HR chest strap, I decided to pull the trigger to track my trail running sessions with GPS. While it isn't as flashy as a Garmin, I've enjoyed all of the functionality of this watch, the GPS has been very accurate and the iPhone app/Polar Flow Sync on the computer provides great feedback. I wish there were cadence capabilities without purchasing the stride sensor, but I haven't felt a real necessity to have it. I did run with a friend that has a Garmin (don't remember the model, but one of the latest) and feature for feature, it was the same. The GPS accuracy was the same and nearly everything identical. He spent $300 or more, while I only dropped $180.

    Excellent Activity Tracker and more!

    The polar m400 has a ton of features that I still have yet to uncover. However, working at a desk job most of my day - this thing will alert you when you've been idle too long. It also works as a activity tracker throughout the day, sleep tracker, and (if you have the H7 sensor) works as a heart rate monitor which is way more accurate than my old TIMEX WR30M. Another thing that makes this stand out is the fact you can connect to the POLAR FLOW app on your phone, as well as the M400 will link with your smartphone to alert you on emails, messages, phone calls etc. You can't email back, message back like on a smart watch by Samsung or Apple, but the alert notice is a nice added feature. All in all, I highly recommend this product but there is a lot of stuff I still am learning about it!

    Too Many Steps To Sync Polar M400 & Virgin Pulse

    Posted
    VirginPulse

    Since Polar M400 uses Polar Flow Software, it does not directly sync or connect with Virgin Pulse. Per discussions with customer service reps, a user needs to set up an account with Polar Flow, and Polar Personal Trainer (PPT) website. Once this is done you will need to go into setting in PPT and select Virgin Pulse as a partner. It will not transfer activities without heart rate monitor. The reason I gave it 2 stars is because Polar needs to have Polar Flow app directly sync with Virgin Pulse. The Polar M400 and H7 Heart monitor work well but I'm very disappointed at the fact that there are too many steps to syncing my device with Virgin Pulse. Until Polar Flow directly syncs with Virgin Pulse, I cannot recommend this product to my friends or co-workers who are also on virgin pulse.

    Pros: The capabilities of this watch exceeded my expectations. I don't use the app for a smart phone. I sync the watch to my computer and it updates my training session, sleep time, and daily activity to my polar flow tracking page. I wear the watch all day and use the heart monitor when I'm doing cardio. I have yet to use the heart monitor while actually working out. I'm improving my fitness before I start hitting the weights. Cons: Only one I can think of is the wrist band. I don't know about other users but I on occasion had problems securing the wrist band. it's thick and not that flexible. I thought after a month of wearing it, the band could become somewhat more flexible but it has not. That is the only "issue" I have with this training watch. I WOULD DEFINETLY recommend this watch. It's very user friendly.

    Good mix between an activity tracker and GPS watch

    • My Best Buy® Elite Member

    I was first interested in this watch because I wanted an activity tracker, but I wanted the look an feel of an actual watch without wearing multiple devices. The many different sport profiles and GPS features are an added bonus for me. I do a wide variety of activities from running, cycling, weight lifting, and different sports, and this watch can track them all and I can track my heart rate. Negatives: -The sleep tracking data is pretty much useless. -Like many others have said syncing data over Bluetooth never works. And Bluetooth smart notifications are spotty at best. TL;DR This watch may not be the best at any single thing it does, but it does offer a wide variety of good features at a reasonable price.

    I upgraded to the M400 from the FT4. I considered the A300 but decided to spend the extra cash for the this model after comparing the reviews. Well worth the upgrade. The heart rate sensor is very spot on and calorie counts are way more accurate than the FT4. The fit of the chest strap is very good. stays put and doesn't move around like other straps. Watch band fit is excellent. It may be too big for wrists around 6" as it has a large face. My wrist is about 7.75ins and it's VERY comfortable. If you're in the market for a fitness tracker and heart rate monitor, this is your watch! The uploads to the laptop are pretty much seamless. BUT remember to sync the watch BEFORE your first workout. Otherwise, your previous workouts will be lost.

    The Polar M400 is exactly what I was looking for in a sports watch. It combines the best of three watches. 1:Smart watch that displays notifications from my IPhone, 2: daily fitness tracker; 3: work out tracker with heart rate. For general fitness tracking, I have the GPS and HRT turned off, which allows for great battery life. when I go running, biking, or hiking, I turn all on and track everything, then I simply sync it to my phone to track my workouts. you can change the workout display to a small set of displays, which include one that I really like so this is ok. One extra feature that I really like is when on travel, I just sync the watch to the iPhone at my destination and the Time auto adjusts also.

    I love that it doesn't use a watch battery, but instead charges with a USB cable. It tracks the route that I walk very precisely on the map. Shows not only how many calories I've burned, but what percentage of those calories were body fat. Seems to track my steps and my sleep pretty accurately as well. Its numerous features are very customizeable. It is rather bulky for a woman to wear. Sometimes has trouble uploading my workouts to the web and requires multiple attempts. I wish that it had the option of vibration for alerts because I sometimes don't hear them. Overall, I like it very much, wear it constantly, and find the information it tracks very accurate and useful.
