      Reliable and Fun at a Great Price

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite Plus MemberElite Plus Member

      I originally purchased this activity tracker to participate in a group challenge at work that measured steps for the workweek. I'm glad I did! One of the biggest pluses I can say about this comes with the battery life on each charge. Being able to have this monitor on you for days at a time without worrying about battery is a gigantic positive! If you are looking to get a very consistent reading on your activity - what better way than truly wearing it for extended periods of time? This activity tracker is also water resistant which is another notch in the "I don't have to take it off for certain activities" plus! So far I have had not had any issues with any exposure to water and look forward to trying this in the summer when swimming may come into my fitness routine. The accompanying app and website for iOS has been a pleasure to use and has a lot of different options to see your progress. Although I don't really use the notification ability - it's nice to know that it is there. The goal reaching alert though always gives me a boost when I realize I reached my goal for the day! One feature that I was very interested in checking out was the sleep monitor. Granted this isn't hooked into brain waves or anything like that, but I must say, for me at least this feature was scary accurate. I know people have had mixed results on this, but to my best knowledge, the "restless" moments during the night were spot on and the hours count was eye opening (both in accuracy and the fact I'm not getting as much as I should be)! The fact that this has been accurate also highlights how I can wear the tracker for days without charging. If I had to charge it every day I'd charge it while sleeping! In terms of fit and feel, there's enough on the included band to find the right fit that I forget that it's even there. Long sleeve and even during intense HIIT workouts, it does NOT get in the way during pushups or any other type of activity that has given me trouble on other wearables. Granted there's no screen so it's a lot slimmer - but at the same time the no screen is also a plus with the slim structure! So if you're wondering why I didn't give it a full 5 stars - I would simply say because of the fact it is somewhat limited in readings. This is not necessarily a bad thing, but it doesn't have every feature you might be in the market for - you may want to get a more advanced model for heart rate for example. For it's class though, this product is top notch and if the feature set fits your needs I wouldn't hesitate at all buying this wearable!

      It's great for what it does

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      Accurately tracks my steps (seems to me its main function is as a pedometer). It alerts me when I've been sitting still for too long... usually 10 minutes before the top of each hour. Tracks my active minutes. For me this is walking or cycling, but it also tracks swimming (waterproof), aerobic exercise, etc. Through the app you can also monitor caloric and water intake, set exercise goals and weight loss goals. I really like the alerting functions that I have tied to my phone. I get an alert whenever I receive a text or phone call. My phone is often on silent mode, so this unexpected benefit was huge to me. It also tracks your sleep (time sleeping, restless and awake). I've found it to be quite accurate though I don't have sleep issues and so really don't use it. Package came with both the large and small adjustable wristbands, so this should fit just about any one. If I had complaints these would be minor. The power charge only seems to last about 2-1/2 days. This isn't an issue for me. Since I don't sleep with it I charge it each night with my phone. Also, I previously had a Fitbit Zip which required a battery. Charging is much better than buying a battery. That said the charge to full seems relatively short (2 or 3 hours). But, I can see if you are someone who would wear the tracker all the time (including sleeping) that this may be a hassle for you. Also, there is no heartbeat monitor or stairs (incline) counter/monitor. I knew this when buying and was not looking for either. If you are then this item is not for you. Otherwise, I think it's great for what it is and recommend it to someone wanting a reliable pedometer with some extra features.

      Awesome Little Device

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite Plus MemberElite Plus Member

      I bought this not quite knowing what it's full capabilities were (I'm a bit of a technophobe). I was able to set it up with even my limited capabilities thinking it was essentially just an electronic pedometer. I was pleasantly surprised it was soooo much more. It allows me to put in my food log and tell me how many more calories I have. It increases that when I continue to do my part to burn calories through walknig or various exercises. It also logs my sleep cycle and gives me goals for how much sleep I'd like to get in. Same goes for weight loss goals. It allows me to tell it how much I want to lose and at what pace I can lose it at. It will also help me maitain my weight when I've hit my goal with a new set of suggestions for caloric intake and output. I kind of find myself excited for my weekly weigh in and watch the little graph chart decline. I also force myself to hit my goal steps when I can actually see what I have left to do. It vibrates when you've been succesful at something (a sort of mini applause). My only frustration is that often there is a delay in displaying how many steps I've put in. Frustrating when you're watching it as you work out and want to see the numbers climb in real time. Can't beat the price and I am working harder than I have before as far as losing weight because I have this little partner helping me and oddly encouraging me.

      I just received this yesterday, in lavender. I have had the one (clip) fitbit for 3 years and finally lost it over the weekend. I love how thin and simple the band is, going from a hidden clip for 3 years I wasn't sure I wanted a bulky piece of rubber around my wrist but its awesome. For those who don't need to see on a screen their progress, this works great. I have my phone all the time anyway so there was no reason I wanted a screen that had to be tapped or pushed to see my steps- just look at your phone. I wear it next to my watch so no need to see the time either. I love that its waterproof as well! Very light weight, very pretty color. and you can pop out the actual tracker and put it in your pocket if need be. It vibrates twice hourly to keep you moving, and vibrates for calls/texts. Very simple alternative if you don't want the bells and whistles of other Fitbits.

      Great when it works

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      I have purchased 3 Fitbit Shines. The first for myself which seems to work fine most the time and 2 more for my Fiance. With mine, I did notice that the app is slow, and seems to have constant issues with synching the info properly but other then that, for $60 bucks, I do like it quite a bit. Since I have liked how mine works, I ordered one for my finace. The first one I purchased for her worked good for a few days but then stopped working altogether. It died when we were on vacation out of the country, so I just reordered her a new one since it was easier at the time and there was not a BestBuy to try and return it to. She received that one last week, but it doesn't seem to be working for her at all and it only stays charged for about 12 hours after fully charged. She can't even wear it to bed because the battery is dead in the morning. Most likely out of luck on the first one I bought since she left it at the hotel since it didn't work but I am going to have her stop by BestBuy and try to get a replacement for the new one. I'll update when I see how they handle it.

      Affordable and Flexible

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      I have owned Surge and Alta before. Both have been great trackers and they still work. As the initial novelty of trackers faded, my real requirements from a tracker became clearer. Having spent countless minutes impatiently staring at my step counts, participating in futile challenges and brooding over my sleep, I was looking for something less intrusive. Timing of Flex 2 couldn't have been...well, timely. The reason I got Flex 2 is because it doesn't have a screen so no frantic taps to worry about. It has a much smaller form factor which makes you forget you are wearing one. It keeps track of steps, sleep and calories without breaking the bank and best of all, the tracker part is removable so it can be easily put in to the wrist-belt or can be accessorized with bangles and pendants (sold separately). I don't have much use for bangles and pendants so I bought a separate clip-on holder to tie this to my shirt pocket whenever I don't feel like wearing it on my wrist. I expected the battery life to be better than Alta but I felt it's the same so no improvement there. Overall this is a reliable tracker at a small price. If not for you, this could be a good gifting item this holiday season.

      Love my FITBIT Flex 2

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      I had the first flex and I really liked it. I don't need to have bells and whistles -- I need to know how many steps I'm walking each day. That is it. What I like about the new Flex 2 is that the band is thinner. I have small bones/wrists so I like the bracelets that are thinner. Also, this feels like different material. The old Flex I had to take it off every single night it bugged me so much; this one I do not have to take off. Some of the problems I'm having is that in order for it to be synched all the time, the bluetooth in my phone has to be on. But that isn't enough either -- I have to log in (I try to every morning) so that I at least get the notification for low battery. The bottom line is this part of the Flex could be fixed (I'm sure w/a software update?). The old flex you knew ASAP if your battery was low. It would last about a week. This one, even tho I sync most days, I don't know if my battery is getting low. Also, this battery expires after about 4 days. The new Flex I can use in the pool WHOOP - this is the BEST part for me personally. I also like the new dashboard where I can see how many hours in my day I've been active. And lastly, I do sort of use the sleep information -- I have no reason to use the food, or water parts. I would recommend this.

      Great for water exercise. It's waterproof!

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      GREAT for my pool time exercise. Waterproof is what was needed for my exercise tracking. I have arthritis and find water exercise is what works best for me. I do pool walking and some laps almost daily. I tried it with my water dumbbells, and I didn't get credit using the dumbbells while standing still. So moving is what it takes with arms and legs. It may not be 100% perfect, but it gives me some credit. I love the sleep tracker. I like also that it reminds me to get up and move if I find myself being lazy. Good motivator! I have been very happy with this fitness tracker. Although you have to have your phone, tablet or a computer nearby to see your accomplishments it's not a burden since most of us have our phones glued to us anyway or a Tablet handy. I wish I didn't have to manually add my calories eaten for the day or each meal. Overall I love my Fitbit Flex 2. Hope they get more variation of colored bands available retail in small and LARGE. Thank You Fitbit for the waterproof band. Negative points: No AC adapter included. I have one with my android phone, but nervous about using it. So have to plug into computer to charge.
