Krazy Klean Pro (10-year warranty)

I wish it would get rid of the old ring unless it takes a while, but at least there’s no new stains so I guess that’s a good thing!

I first put it in the tank, and no difference. I cleaned the ring with the pumice stone, and in two weeks not more stains. Did not give it time to work? Do not know, Still skeptical, my other two bowels have no stains in them, and I have not yet opened up the boxes and put them in the tanks. I think the people are great to work with, and they respond with every question.

31 days is not 10 years, but so far they are working in all four of our toilets. No stains and no need to add bleach to get out stain on bottom.

The product works as suggested; it does not leave behind any more rings, and the bowl looks clean. Need to hard scrub the previous line, though, thought a scrub sponge was supposed to come with the package. it would be 5 stars, but the product is a bit expensive.

Cleans good

So far, so good! I’ll see how it is in another month or 2.

5 stars I may have to use it

I've tried it all, bleaches, tablets, fizzy things, etc. and I have always ended up with that horrible ring in my toilet. I kept reading about these and though I was skeptical I make the purchase. After scrubbing the purple rings from my most recent attempts at drop-ins with pumice stones, I dropped the Krazy Kleans in my two toilets and it's been about 3 weeks--without a shadow of a ring or need for scrubbing. Honestly--I check every day and I'm amazed!!
