    This activity tracker was good at first but I soon realized I should have purchased the upgraded version. While this would probably do the job for the average customer, I needed the heart rate tracker for many workouts. Overall this product was good, I just needed a little more in depth activity log.

    I have been using this product every day since purchasing it. It's a good starter model although if the higher end models had a distance walked/bike/run feature as well as a heart rate mode, I'd spend the extra money. Also the fact that this isn't advised for use while swimming was an unexpected let down.

    I have had good success with the Flex and I really like the app that syncs with it. It's accurate and user friendly and has been eye opening regarding my sleep pattern and average activity during the day. It is quite comfortable and I often forget it is on my wrist.

    I love it. It keeps track of steps, sleep, activity and exercise, and your calorie and water intake if you choose. I use it primarily for step and activity tracking, but the sleep tracker is great for monitoring how much quality sleep your getting.

    I lost my other tracker and ended up with this one. The down fall was that you have to make sure to unset it once you are awake and out of sleep mode. I was used to my old tracking device and didn't like the app. It didn't show as much as my other, but since the updates to the app it is much better.

    I really like the fitbit, however, I did find that the bands don't hold up very well. Not sure if it was just me or if other have had the same problem? The part that you put the bit in and out of in order to charge, ripped :( Other than that, I really like the product and the app and it works great.

    Nice easy product. Make sure to buy this version instead of the one with the actual screen. That just looks bulky and you can use your phone app to look at stats instead. It doesn't tell me when the battery is low so I've had times where it didn't track my movements for that day. I also think it gives erroneous results for calories burned. It seems way too high, but can't be sure. I do like the fact you can put your weight in the app, so you can see if the steps you do makes a difference. I also don't know if you exercise if it accounts for the calories you burn if you aren't actually running/walking. But in general it helps see how much work you are actually doing, at least an estimated version.

    I walk a lot at work and I wanted to keep track of my number of steps, miles walked and calories. This works perfectly and I am happy with my purchase. I should warn you though that the changers can get lost because they are so small. I lost mine within the first week and I had to purchase that separately.

    The Fitbit Flex is a good fitness product, however, for beginners I would recommend the Fitbit Charge or Charge HR. In my opinion the Charge products are more user friendly as you can easily track your activity throughout the day.
