Krazy Klean Pro (10-year warranty)

I live in an area with incredibly hard water that results in clogged showerheads, dirty showers, and rings of mineral buildup in the toilets. I was excited to try these because it's a pain trying to keep the toilets clean, even when they weren't being used for, ya know...The rings would build up no matter how frequently I seemed to scrub the crapper. While these do not completely prevent the mineral buildup in my experience, they have made a dramatic difference in how much and how quickly the mineral rings are building up, and the ease of scrubbing them away. Mineral buildup is happening much slower, there's significantly less, and its been much easier to scrub it off. Previously, buildup would occur in a week or less; it's been 3 weeks since I put these in all my toilets and I'm only now starting to see a faint ring in the bowl. Very grateful for these weird little pods and will be recommending them to friends in the neighborhood!

This product delivers. It’s simply an amazing product. I’m completely satisfied.

Our water is DITRY from our well. That being said, our toilets would get grime and red from the iron and minerals. Since using this product our toilets are SPOTLESS.

3 weeks in and no water rings have returned! Looking good so far!

Its been a month since I’ve installed the Krazy Klean units in the tank. So far all is good and clean. Will up date in another month.

We purchased this product thinking it was too good to be true. With three small kids and a single bathroom, we were scrubbing the toilet every few days and it still wasn’t sparkling clean. The Krazy Klean has been in our tank for 3 weeks now and we haven’t had to clean it once!

It's working, scrubbing toilets way less than before

Been using it a week. I started with clean toilets and dropped the Krazy Klean unit in each toilet tank. We have 3 children and 2 adults so our toilets get plenty of use. After one week, the toilets still look perfectly clean.

It claims that you never have to clean the toilet again, but that’s just not the case. Yes, it has kept the rust-color ring from forming, but it still allows grime to accumulate on the edge. Still a good product, but it only keeps the toilet clean for about a week.
