I had my first WL-50 stop charging, I figured i was just unlucky so i got a second, for about 2 months it worked like a dream then the bug stopped charging, when in the USB it charged fine, then suddenly it stopped working altogether, the bug was green the cradle was dead, even the pass through didnt work. I am currently sending it back, i wont want another one, Thomann as always very professional and efficient.
