I bought this band to replace a fitbit I had returned. I had 3 fitbits in a row and the band broke on all 3. I couldn't bring myself to buy another one and I didn't want to spend hundreds of dollars. This tracker is cheap and has almost all the same features as the fitbit. I don't think the sleep tracking is as accurate and the reminder to move I don't find as useful but otherwise it's a good substitute. For the price it is fantastic value. The band so far is good although difficult to get the tracker in and out. Would highly recommend this product for anyone who wants what a fitbit alta hr does but doesn't want to spend all the money.
