My cousin had one of these for his stereo. Are they any good to have? Anybody have problems with them.

It should be fine.

Only problem is that if it trips or is used as a switch, you've decreased the reliability of the breaker and it really becomes a gamble as to whether or not the breaker will trip when it should. If you want one as a switch, I'd add a fuse as well for safety. Fuses are both dead reliable and cheap considering that they shouldn't trip except in an emergency. In the event of that emergency, replacing the fuse that saved your car is a bargain.

I use them, they're fine. It's convenient for opening the circuit if needed too.
