Of course, all this fun could not come without a price. My yellow pad started getting really wonky near the end. I thought maybe the piezo got loose or something, but upon popping off the head and taking a look around, the solder on one of the wires came undone. It's not a difficult fix, but I won't have time to get to it today. The good thing is that it'll probably be a stronger hold after I fix it than it was at the factory. My red pad did the same thing about 6 months ago, and I soldered it back on with a friend and it's been perfect ever since.
