Doesn't correctly sync information especially with sleep and the dates are always inconsistent inconsistent sometimes it doesn't register my steps because I have my hand on a cart at work and I just use it at this point for a watch instead of instead of for my fitness because it doesn't have the same quality as it once did. I've even went out and purchased a brand new one and it just seems like an update is needed there's none available just over fitbit it's not the same as it once was
