I really like the fact that this is a low-tech timer. It's hardy, and you don't have to worry about batteries or anything, so for that reason, I'm glad I purchased it. My only complaint is the suction cup. You need a PERFECTLY SMOOTH tile for it to stick, and my shower tiles have a SLIGHT texture to them. I have to prop the timer up on my soap holder to see it, so I've made it work, but it's a minor inconvenience. For what's being charged for such a simple device, the suction cup could at least work.
