Review: Fitbits are very useful if you want to track your workouts and sleep cycles! - 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
Review: Very disappointed with this seller and product I received - This was a replacement for my watch that had a cracked screen. Looked great, packaging looked new, everything worked until I tried to charge it. It took 6 overnight charges to finally reach 100%. The problem I have is the watch will not hold a charge longer than 1.5 days. It sucks having to charge EVERY night to be effective. My previous watch needed a weekly charge. I called tech support and the return line - what a joke! I got a call center where I could hear the next two conversations better that the one I was on. I got nowhere! DO NOT BUY a refurbished item from this seller

### ⭐⭐⭐⭐⭐ Vital part of my wardrobe.
*by M***6 on February 22, 2024*

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.
