Bests & Worsts Reviews from Amazon

Was working well but now it's almost completely useless except for telling time. No HR function, no exercise tracking, won't change from factory default clock face, and it's slow to sync less than 2 months after purchase. Manufacturer offering to send new one in 2 weeks(!) with the same old warranty. Definitely would not recommend this product as it's quick to break and manufacturer is slow to respond. After 4 years as a fitbit user I'm disappointed. Save your money.
