Thank you, I will definitely get one of these. I have heard of them, but don't know much about them. I did a quick google search and found this nice little piece of advice: Be sure to use separate stones for toilet cleaning and body use. Do not use the same stone for both purposes.
I'm so ready for these rings to be gone. They are just rings, except for the toilet upstairs. That one had a broken part when we moved in and the people who lived here apparently just left it sitting there and so it is discolored on the bottom. It was a $5 part.
Oh well, it's mostly just the kids who use that bathroom.
