Best Review
Customers find the fitness tracker does everything they need and is easy to use and set up. The device is well-designed, comfortable to wear, and considered the best in the Fitbit series. While some customers report great battery life, others mention it doesn't last long, and opinions on value for money are divided between those who find it worth the price and those who don't. The durability receives mixed reviews, with several customers reporting that the band has broken.AI Generated from the text of customer reviews
