- Beware Fitbits Die After 15 Months- July 6, 2020
Do not buy a Charge 4!!! Similar to many other reviewers my Fitbit Charge 3 lasted 15 months and then turned off one day to never turn on again. I was warned about this with the Charge 2 reviews I read when trying to decide but figured I would give the company a chance to release a better product in the Charge 3. No luck folks, be very cautious when buying a "Charge" Fitbit they only last just over a year and then support offers you a small discount on their other products which is a bit insane to be fair. Basically they say "Sorry our first product was so expensive and unreliable can we offer you another another equally expensive and unreliable product???". Pass on this product.No, I would not recommend this to a friend.

- Useless as anything other than activity tracker.- September 3, 2020
If you only need this to be a step counter/calorie counter, then you're in luck. Sadly, it is horribly over-priced if that is all it can do. I have had mine for a few days now and have had no luck with all of my trouble-shooting in getting it to receive notifications for texts/calls/calendar updates. I've gone through all of the suggestions that the Fitbit message boards suggest, and nothing works. I have an iPhoneX, which shouldn't be an out of date device preventing these features from working properly. I got the more expensive Charge 4 so that it could be a nice peripheral to my phone. It sadly is anything but that, and will be returned.No, I would not recommend this to a friend.
- Solid fitness tracker- March 8, 2021
Great tracker! This was a huge upgrade from a much simpler Fitbit Flex 2 (which even didn’t have a screen). The heart rate detection works well, the screen can be configured to show a has a variety of details via the app (my favorite has time, heart rate, calories, steps), and the battery lasts about a week. I haven’t really used the smartphone push notifications on the tracker but that’s because I usually have my phone on me. The only downside is that the wristband that came with the tracker broke within a few months, but the wristbands are easily replaceable (snap off the tracker) and the third-party replacement ones are quite inexpensive.Yes, I would recommend this to a friend.
