Not Worth The Retail Price
The Fitbit app doesn't allow the user to customize the data presentation and has a low quality, non-intuitive user interface. I would NEVER pay retail for their overpriced product.Verified purchase: YesCondition: Pre-owned

Works great for me
So far I have not had any issues with the watch. I have never owned a super expensive Apple or high end one so I can not compare it to them, but this one has all the features I need and compared to the others I owned and my friends Garmin watch it is just as accurate.Verified purchase: YesCondition: New

Works well but needs to be charged daily!
Fitbit arrived when promised. Being an older model, works well but only holds a charge for just over a day. Has to be charged every night. Next time will pay more and get a brand new model from a shop or fitbit online.Verified purchase: YesCondition: Pre-owned

Not worth the upgrade from 3 to 4!
This Charge 4 is a replacement for my Charge 3. When I purchased the Charge 3, it was supposed to track oxygen levels, but never did. I wanted to track my oxygen as I am asthmaic and have chronic bronchitis. Knowing where my O2 levels are is of importance to me. I was excited to use Fitbit Pay with the Charge 4. Very disappointed when none of my banks are a part of Fitbit pay. Can not use my Fitbit to pay for anything! If this is a feature you are wanting to use, do your homework. Wish I had done my homework. Other than the oxygen levels, it is just like my Fitbit Charge 3. Would not have upgraded if the screen had not become so faint that I couldn't see the time!Verified purchase: YesCondition: Pre-owned

Charge4, way better than Charge2 or 3. Adds gps and spotify control
Great fitness tracker. I have had the Charge 2, a few Charge 3s and now a Charge 4. The '4' adds gps tracking and ability to use with spotify. Like all fitbit units the heart rate can lag somewhat for instant read outs. Over all I am not sure why anyone buys the Charge 5, since you need a monthly subscription to get full functionality. Use the fitbit app w/phone for best experience. Seller shipped product quickly and was a great value.Verified purchase: YesCondition: New

Great tracker and watch
It replaced my charge 3 and all the bands I have collected fit it. It is great, the display is clear and the letters and numbers are very well defined. In my opinion it is the best tracker/watch availableVerified purchase: YesCondition: New

Great fitness tracker
Great for helping keep track of activity level and sleep patterns without being overly complicated. My one complaint is the trade-off in being small makes it a bit hard to read on the face, but you can use the app to review stats.Verified purchase: YesCondition: New
