This product does exact as it claims to do. If you have yellowing stains. Within a week of using this product they will be gone. My teenager's love these in thier bathroom. Warning: Do not use this product if you have dogs, or any animal that may drink from the toilet. For anyone else, the bleach smell is very strong in small bathrooms or bathrooms that are seated next to the bedroom.

This product damages the rubber seals around the fasteners that secure the toilet tank to the bowl. The rubber is crumbling and flaking away, and water leaks from the tank. There is no warning on the product packaging that this may occur, but a telephone call to Clorox customer service resulted in their acknowledging the problem and refunding the purchase price. Repairing the leak requires disassembling the toilet tank from the bowl and replacing the seals and fasteners--not a pleasant task. I do not recommend this product.

I had hurt myself so I couldn't clean a regularly a normal and noticed a ring developing around the toilet bowl between cleanings. I felt dirty because I wasn't used to seeing anything like this. I bought these and dropped one in the toilet tanks when I cleaned the toilet. I've never seen that ring in our toilets again. That showed me that these really work.

This product definitely kept my toilets clean. However, it ruined the insides of all three of the toilets. I had a brand new toilet put in and had to replace the tank about nine months later because of this product. I had two different plumbers tell me these tablets were the reason and to never use them again.

Work great for our fountain

The Clorox bleach tabs keep the toilet clean and the bleach aroma is refreshing.

The strong odor of bleach is just too strong for home bathroom use.

Works well but smell is very strong

Keeps toilet clean and removes stubborn well water stains

This is good value pack. They keep toilet bowl clean and last longer compared to other brand
