However, once this (big) problem solved, the unit keeps its promises. He quickly locates, it is sensitive, it has all the expected features. I had a similar device (i-gotU GT 800 pro) that gave me satisfaction.

Other benefits of Canmore battery is actually interchangeable plug is a mini-USB (stronger) ... It's just a little Plue cumbersome. In short, a very good choice if you want to share things.
