I used these in the toilet tanks for about 5 months in our home we use as a mountain Airbnb. Since we aren’t there we didn’t know there were problems, when we went home to check on things we realized the rubber seal in 2 out of 3 toilets were eaten away and had been running water nonstop, it has flooded out septic field and infiltrators, we now need to have our entire leachfield redug. The water table is also extremely low where this house is and with the toilets running nonstop for a few weeks it ended up drying out our well. Please learn from us and don’t use these in your toilets!! We have the new dual flush toilets so not the standard big rubber flappers, a very thin rubber gasket that was completely eaten away and missing, such a terribly unfortunate thing to happen! Don’t let this happen to you! Wasting water is terrible wether your on city water or well water!!

I love how this product works but I am very sensitive to smells. This keeps toilet clean but my nose can't tolerate it. I try to wash hands use toilet paper to flush then run. Won't be repurchasing BC of this. But it's a great product if you are not sensitive to bleach.

It does help keep the bowl clean but the smell is like a public pool after it just had way to much chlorine put into it. It is strong enough to make me wonder if the fumes are harmful to my health. It would be nice if the water in the bowl were blue and there was a pleasant or no smell at all. The cleanliness is not worth it in my opinion.

Installed a whole house water purification and softener system several years ago. We started noticing blacking rings in the toilet at the after. The tabs solved the problem. Only issue we have, is if we have them shipped, alost half of the tabs are cracked into several pieces, and they don't last as long.

Really helps to keep the bowl clean. Works much better than other brands.

Works the way it was designed to.

Love these shirts, for me not my man!!!

its a waste of money, not seeing its working, Sometimes observing acid kinda smell.

Wish I could purchase this at the club and not online

Great easy way to keep your toilets clean
