I was really excited to find a tracker for our kids that wasnt ridiculously priced, but now i know why. The biggest problem is actually the app. It takes forever to sync and won't stay connected (but make sure it is not charging or it won't do anything, the directions dont tell you that). But the band itself the biggest complaint is to have it snug enough that it doesn't slide up and down his arm, his skin would get pinched putting it on because you have to keep your fingers under it. Poor design for kiddos. We are sending it back, along with the one we got our daughter. Very disappointed.
