Toilet Bowl Cleaner Chem-Free 50,000 Flushes

I have used these for at least 12 years. We had always moved about every 2 years, so never realized how well they had been working until we were in the same house for 6 years and couldn't figure out why the toilet bowls kept getting so dirty...I had never had to replace them before. They do a great job and they don't have any kind of bleachy or chemical smell!

might have worked well for other people, but didn't do anything but sit in the tank :(

So far so good! We have a lot of sulfur and iron, and so far (just a couple of weeks so time will tell better), it's all clear In the toilet bowl! A great improvement.

I used these, or something similar, in Hawaii for years, but these don't do anything! It doesn't matter if its a frequently used toilet or not, i still end up having to clean them once a week to avoid a red water line. Don't waste your money.

Note to self: Read the product description before ordering (amazon one-click makes it far too easy to order based on reviews alone).Let me start by saying I'm not accusing the seller of anything. I was a sucker to buy it, and I have no one to blame but myself. But if you're about to buy it, know what you're getting.What this product doesn't have:- Any chemicals- Any ability to clean anything- Any relation with toilets. "50,000 flushes"? That's just brilliant...What this product has:- The ability to stay on the floor of the water resovoir (in other words: it's heavy)- I am yet to find out anything else. Maybe communicating with aliens? Perpetual motion?"magnetically cleansing"? Yeah, right. I guess I fell into that one. Gotta run: this guy has a bridge to sell me. Amazon reviews give the bridge 5 stars. And free shipping!

I have used this product in 10 toilets in my homes over the past 15 years. It works just as described. Thanks for making this...Lasts a really, really long, long time. I highly recommend. It is safe and without toxic dangerous chemicals.

We have a hard water well and septic system and with these our toilets look like city water toilets - no stains. I use two in each toilet tank and never think about them. We don't flush the toilets every time and if we did the bowls would probably never need cleaning, but the cleanup isn't of mineral stains so it's easy. Just Bio-Kleen soap or other cleaner and a swish with the brush.
