[This review was collected as part of a promotion.] I like the form factor of the tracker but it doesn’t work if you plan on putting it in a wallet that you keep in your back pocket. The first problem is that the button that turns the tracker on/off and resets it will keep getting pressed turning it off and on and even causing it to be reset occasionally. The button needs to be relocated to prevent this. Finally after using it for about 2 weeks it seems that something inside has been damaged and it now beeps randomly when it is touched or moved.
