Fitbit Flex 2 Smart Fitness Activity Tracker, Slim Wearable Waterproof Swimming and Sleep Monitor, Wireless Bluetooth Pedometer Wristband for Android and iOS, Step Counter and Calorie Counter Watch

I love Fit bit, and already had a Fitbit One when I purchased the Flex 2. The One I have had for several years & it's been very dependable. I have even accidentally washed it in my washer & it still works (although I wouldn't recommend)! I got the Flex 2, after hurting my back and needing to do aqua therapy. It works great, & tracks my steps & swimming without any problems. Although, be sure when you first get it to go into setting & tell it what you want it to track. It is very lightweight & comfortable. The lights tell you if you got a call or text, but I don't carry my Note to the pool area...so I don't worry about it, until I am done. I wear it all the time (accept while charging), tracks sleep & you can get the same vibration for the alarm. It is much easier than moving everything to the armband for the One. Now I only use the One when the Flex 2 is charging. Both Fitbits sync to one account...you just can't use both at the same time. I use the Flex 2 during swimming, then dry everything off as recommended. I also don't put it in the hottub/whirlpool or sauna, etc at the gym because the high Temps are not recommended. But I highly recommend if you are looking for a tracker.

About 9 months ago, I decided to get a new fitbit and saw a sale on Amazon from 1seller1. Having used this product in the past (flex 2 received as a gift and earlier model from Best Buy store) I purchased this new fitbit flex 2 hoping to motivate more walking-instead I've had annoyances and aggravation from trying to get this to work. Essentially it is junk. When it first arrived it would not charge-pretty much not at all.After hours of having it in the outlet charger to no avail I tried the laptop charger. So, I arranged to return it for a refund and received a refund label (so that was good) but since I could not locate the original packaging was unable to do so. I found the packaging later but it was too late. I have no way to contact this seller. Later, I tried again to charge it as I saw one light and had a glimmer of hope it might work. Having thrown away good money on this product, I tried in vain to get it to work. I managed to get it to appear to have charged it minimally to get a flashing blue light and the occasional buzzing. However, as it turned out, that did not mean it would be "findable" by the fitbit app each time. Only once was it-to my phone app-never the window app on my laptop with the non-blue tooth device dongle--but regardless of the perceived small victory, the battery failed to ever charge sufficiently to sync ever. So my conclusion is: this must be a knock off or one of the"made in china" poor quality and defective merchandise units-- in comparing this seller's product to the ones I previously purchased at reputable stores (which actually managed to work all the time unlike this which never worked) I would like to get a refund but won't hold my breath -despite the UCC which requires a refund for defective products within 1 year. That is a huge drawback to buying on Amazon instead of the old fashioned trip to a physical store. BUYER BEWARE.

I recently started participating in an at-work health program and was very interested in tracking my steps and sleep, so I started researching the Fitbit models. I love wearing/accessorizing watches, so I knew I did not want a Fitbit that was too large or had all of the timekeeping functions. The Flex 2 was absolutely perfect! In addition, I went with the lavender band because I am very fair skinned and wanted it to blend nicely with my skin tone, but also work with different outfits. I will probably be purchasing the navy blue band as well for a little variety.The functionality of the app is excellent. I love seeing the sleep habits and am considering using the water tracking and other dietary functions. It really is way more than I anticipated as far as options for tracking! The battery lasts a loooong time. This first time I was able to go almost 6 full days, but I think it says realistically it's five. That's still great! And it only takes a couple of hours to charge, so charging it at my desk while I'm most sedentary is great. Overall I'm very happy with this purchase and especially for the price, I think the features WAY out weigh the cost.
