We have 2 full bathrooms in our house. Our toilets would get a ring at the water line within a week of cleaning. The toilets were border line to be cleaned when I put the Krazy Kleen containers in each toilet. and the rings were gone in 4 or 5 days and 25 days later the toilets bowls are completely clean. Now I don't know if it will last 5 years let alone 10 years but, as of now there is no toilet bowl scrubbing needed in my house. It is rare now a days to buy something and it work as advertised so we'll see. Good job so far!
The 3 toilets 🚽 in my home are all without a ring and this product is helping it to stay that way so far it couldn’t be easier than this everything is so nice and clean
