They do work, but to say you will never have to clean your toilet again is a misrepresentation.
I was skeptical at first. This product works way better than just using magnets.
I have very hard but treated well water. I haven’t had to clean my toilets since I placed this product in my toilet's. Previously had to clean several times a week to keep from having rust and ring. Very very pleased!!!!😃. Hope it lasts. Well worth the price!!!
My toilet is so clean I could drink the water out of it! Ha!
