Such an easy way to keep toilet clean. Just remember to always close lid before flushing. Otherwise this product - and everything else that was in the toilet bowl will get vaporized all over the bathroom! We have used these for many years. Only a faint bleach smell yet kills almost 100% of pathogens.

Bought this product this spring for use in the summer house. Plumber is replacing gaskets in the toilets as one toilet gasket failed and the toilet leaked in a spare bedroom and now damaged the ceiling in the family room. As I did some reading it appears there was a lawsuit in 2010. Why did you not pull this product from the shelf or solve the problem and keep selling it. Always a trusted the Clorox name. Not happy

We have used these for years in toilets that are used often, and have found them to be very effective and true to the description. I've recommended them to family members, but have heard that they're not so good for small rooms (if you don't like the smell of belach) or for toilets that are not used often--the bleach may start to eat away at the rubber in the tank. We, however, don't have any problem with the smell, and haven't had to replace any tank parts because of deterioration.

I agree with others. I had a costly pluming bill yesterday because of this item. No where on the packaging does it say that it will destroy the rubber in the tank causing the water levels to decrease thereby having the water to constantly refill the tank which then increases your water bill to also go up! It works but is not worth it.

love the fact that i dont have to scrub toliet everyday, i watch take care of 2 toddlers(grandchildren) while parents work plus am care provider for mom with a ton of medical issue so anything that i can use to make my day a little easier is great. i have used clorox products for as long as i have can remember. love them

I have been using the for over a year. I had been taking a record of how long they last. well it was only 18 -to 20 days. not good. says it works up to 3 mo., well that is true. last time for me. I want all my money back. for over a year. we have bought at least 12 or more over the years time. sad...…...

These are pretty good. You clean the toilet bowl first, then add the puck to the tank. I haven't had any calcium or grime build up since putting them in 8/4/22. I'm sensitive to odors and noticed they did have a strong chemical odor the first week. I could smell it as soon as I walked into the bathroom. Now I don't notice the odor except when I flush.

We loved this toilet bowl cleaning tablet until we had one gasket start leaking and then noticed deteriorated gasket parts in other toilets ( black crumbs). We need to have all gaskets and seals replaced to avoid costly leaks in the future by what we have read here. The tablets do a great job cleaning but seem to be destructive over time. Too bad. We were very pleased until now.

I was having to scrub my toilets every two weeks due to a brown ring that would form even in the unused bathroom. I dropped one of these in each toilet 6 weeks ago & the toilet rings stopped. I'm waiting to see how long it will actually last before I have to put another in. These things are great!

[This review was collected as part of a promotion.] I am an avid Clorox product user and am typically happy with the products. However, I purchased a faulty tablet as it did not dissolve and it got stuck underneath the boot of the tank causing the toilet not to flush properly until the plumber removed the toilet to find the undissolved tablet. I will not be purchasing this product anymore. I'm pretty disappointed.
