I was very skeptical at first. One toilet in the house was literally black inside, and I didn't scrub it for probably like 2 months after putting this in and didn't really see a change, but finally broke down and scrubbed it and all that gunk fell right off and has been spotless ever since. I'm making toilets look brand new again! I'm buying them as gifts for people, using them in the house, at work, I love them!
Placed nearly 3 weeks ago and toilets are sparkling! I have hard water where I live and toilet rings are very common….not in my house!
Put it in my most used bathroom about 2 weeks ago and have not needed to clean it, yet! This is impressive.
