This stuff works really well. I add one to the tank at the beginning of each month and never looks dirty.

I can’t smell my toilets fresh like I used to.I love the bleach smell and these seem to not be doing there Job.

I have Airbnb units and these are always in the toilets. The bowls stay clean, and fresh between weekly housekeeping....Yeah!

Works just like advertised. Been using this product for over 10 years. Always buy at Sam’s Club because you cannot bet the price.

I like the way these keep my toilet clean. The process at Sam’s is much better than regular retail stores.

We’ve used Clorox tablets for several years now, work very well at keeping toilets clean & free of bacteria.

Love this product, only wish they carried it in store again! However, even though I purchased this on line it arrived very quickly!

We like that it works for weeks keeping the toilet clean and fresh. We also like that it is safe for our septic tank too.

Keeps the toilet clean. The only drawback is the it has residue on the tank and that gets discolored the longer it doesn’t get cleaned off.

Love these. Keeps toilet rings from showing up. Wish I knew about them years ago. I will definitely be buying these forever.
