Review: Vital part of my wardrobe. - I was diagnosed with afib. This permits me constant status of my heart rate. The band wears out about once a year so I keep a replacement on hand. After about five years the connection on the watch to the band broke and I needed a new one.
Review: Awful customer care - I'll never buy another fitbit product. I purchased my 2nd fitbit after the first one broke (plastic where the band clips to broke). The first one I had awhile so I picked up another one, no big deal. The 2md one lasted 2 months. During the day the fave wouldn't light up. Per the app it was still tracking my steps. When I got home and threw it on the charger it wouldn't take a charge. Onto customer service. I went threw the app and called them. Answered all the questions and completed all the requests. They said I would get an email. The email I got was that it's not under warranty. And just like that I was out of luck and they haven't responded to any other emails from me.

### ⭐⭐⭐⭐⭐ Fitbits are very useful if you want to track your workouts and sleep cycles!
*by W***Y on January 14, 2026*

I absolutely love Fitbit Charge 4. Just the right size for me. This is a great buy, but I'm having to replace this refurbished one and will purchase a brand new one. It's very easy to use. Now you have to pair with a Google account. The sleep information is very helpful
