Whether I like it or not a lot of water tends to sit on my countertop, past soap dispensers rusted and made marks on it. They've also rusted at there the pump twists onto the base. I've only used this for a week but from what I can tell neither of those situations will be an issue anymore, I'm happy that it's a plastic material and I lie that I can see how much soap is left.

Pros: Won't Rust, Can see soap levels
