I bought the four pack two for my aunt two for me and I can tell there’s a great difference. I did a little scrubbing with a pumice stone, but I have to say I’m very pleased. Thank you very much, telling all my friends about it.
It’s a wonderful product. I am so happy I bought 2. One for each bathroom
Was so annoyed after purchasing my two new toilets that they formed a ring so very often! Tried the blue tablets and they didn’t work either! Krazy Klean has been excellent so far! Have had them a few weeks and voila! No ring in the toilet!!’
At this point it has been installed, but we are out of town, will be able to see it work when we get home
