This is the second pair I’ve used the first pair was Rigid and didn’t fall over of course couple years down the line I bumped it one too many times and broke it off I glued it back it works but I got a new pair this pair that fold over much better. It ran out of juice because I didn’t have 100% charge at the first band rehearsal, for the gig ahead and fully charged and it work for a couple hours and the gig was over so I don’t know when they would’ve died. So far I’m pretty satisfied, lol I can’t find anything to complain about but stay posted.
