Can’t give it 5 stars yet, as I haven’t had them in my toilets for too long. So far I am not noticing the usual build up I get in my toilets from our well water. If it continues to work for years, as they claim, I will give it 5 stars then!
I put them in three toilets about 2 weeks ago. So far, our bad toilet is slowly looking a little better and the others have remained clean.
We have hard water & a lot of minerals in our tap water & even though I clean my toilets at least 3 x a week, I couldn't keep the crusty rings from developing at the water levels. Krazy Klean has helped immensely! Thank you for a great product.
