It's totally broken.Because it's not water proved,and by water proved I didn't mean throw it into water. I use it normally.While using some water coming from my mouth get into it and its broken.Can't believe that,it means U can't use it, otherwise the little water fall off from your mouth will break it.what kind of product is that? Can U image a raincoat can't use during a rain? I give 2 star instead of 1 is because it works for two month at least 30 times until it's broken.
