    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 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.

    Runner, cardio, weights workout

    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.

    Great for running/GPS tracking

    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!

    Exceeded my expectations

    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.

    Best Fitness Technology Purchase

    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.

    First Polar Watch

    This is my first polar watch. It has many great features making it a great value for the watch. If the heart rate monitor was attached with the watch that would be a plus, hoping that is included in a future Polar. Other than that the watch with the HR makes it a great activity and exercise tracker. It is very accurate and keeps track of your daily activities 24/7. It also allows you to customize exercises to give you more details of your exercises, something you may not find on higher end watches such as the Apple Watch. You can also setup to receive notifications from your smartphone. Great buy and have enjoyed using it for my daily exercises and activities.

    I saw a few negative reviews about this and how it syncs but has worked flawlessly for me. Syncing is not automatic but works very well. I love the GPS tracking accuracy. The iPhone app provides great detail and works much better than ifit which I used with my training bike. The only issue that I found is if my iPhone is nearby and Bluetooth is on, the heart rate transmitter will not pair with the watch. Turning off the iPhone Bluetooth solves that issue. Once the transmitter pairs with the watch, then you can turn Bluetooth back on the iPhone. Great product and glad that I did not simply replace my HR monitor with the same thing as previous.

    This is a great fitness HRM and for the price, it's hard to beat. Battery life lasts up to 2 weeks which is remarkable compared to similar products. Smart notifications, GPS, customizable data screens, sport profiles, and sleep and activity tracking work great and haven't had any problems from day 1. The app is very functional but the sleep data is not as robust as some others which is not a big deal for me. I wish there was a vibration function but this is also not a deal breaker considering the price. Overall happy with this purchase and love seeing software updates to further enhance the product.

    I've been using this a little over a month now and am very pleased with it. I have been using Suunto watches to track heart rate and calories for my daily workouts but had been having a lot of issues with the chest strap not registering or losing connection in the middle of a workout. After reading lots of different reviews I chose this one and it did not disappoint. Great accuracy in recording daily steps and the heart rate during workouts is 100% on point. I had no idea it would link up to my phone and provide alerts so that has been an even better bonus. I would absolutely buy this watch again in a heartbeat :o)

    I am an owner of a moto 360 first generation smart watch. I've owned it for over a year now and I've loved it. Then I started working out, and runnign more. I then purchased this watch with sensor so that I could better keep track of my fitness. I prefer this polar watch over the moto just because Its nicer for working out. In addition its waterproof which I need for my job and I dont feel like it will scratch as easily as my moto would. Great watch if you're into working out. Definately choose it. There could be improvements like a date displayed on the home screen. Other than that I love it. :D

    I did a review of most hrm and ended up with 2 candidates, m400 and garming foreruners 25, do to the comparable features as, mutltisport, gps, etc. finally, i decided by m400 Great to selup the sports of you interest and also a deck of screens within each sport with all the information that you select to see. Battery performance may be an issue if you use gps and ligths on on night rides. Nice indoors training options. Good ios app

    GPS for outdoor running and cycling is accurate. Bluetooth works well. Polar Beat, Polar Flow, and Polar Web add to the watch and make it easy to see trends, data, etc. It can be a bit confusing at first setting everything up and understand how it all works together. But there's a lot of extra features so it's understandable. My last Polar lasted me 10years. Hope this can do the same.
