Krazy Klean Pro

So I waited 3 months before writing this review to see how well they worked. I can honestly say I am pleasantly surprised at the results. I normally have horrible hard water stains that appear after a week or 2 of scrubbing them off. After 3 months of dropping these in my tanks, they have not re-appeared! My toilets look amazing. I was hesitant to spend $99 for all three of my toilets but this product is well worth the money. I would highly recommend them if you suffer from hard water stains!

I was skeptical, but this works, 2 weeks in and no ring. We have very hard water where I live and this is a blessing in fact I’m ordering my 3rd one.

Very pleased so far have been using for about 3 weeks and monitoring bowl. No issues or need to clean showing up.

It works pretty well considering I'm on Well water with a high concentration of calcium.

It does keep that nasty out of my commode bowl. I have to say I was shocked at how well it works.
