Query: Casio goes forever

I've been pretty good about keeping this dry, but have done a ton working out with it, so it's seen it's fair share of sweat and grime. Keeps on ticking... in a digital sense. Light on it is pretty weak... hardly lights up the whole screen - that said, it's ten bucks... hard to go wrong. for a cheap watch, it's great. I do sometimes wish I had spent a couple extra bucks on one that could go in the pool/shower with me.
