The two channels aren't a problem at all. The biggest problem is the general poor quality of the chatterboxes. I have four of them, and at any given time at least 2 of them are broken. The most common problem I have with them are broken potentiometers. Just this last weekend we lost 2 units over the course of 3 days. One lost a battery, the other started screeching like an angry monkey. I suppose it could have been a battery issue too. Of course, BK's was fine the whole trip. :smash:
