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.

I have been using these bleach tablets for a couple years and absolutely loved them. However, literally all of the rubber components and valves inside of my toilet tank have disintegrated to dust due to the long term exposure to these bleach tablets. It's been very frustrating having to replace all of these parts. My toilets are only a few years old, so the rubber should still be holding their integrity. I am no longer going to use these because it's a bigger pain to replace all these toilet parts then it is to actually clean the bowl.

We have 4 full bathrooms and 1 powder room that we use these beach tablets in for approximately the last 12-14 months. Each of the bathrooms are used numerous times daily. I recently found water on the floor in one of the bathrooms, surrounding the rear of the toilet, and after a close inspection of the toilet learned that all of the toilet's tank components seals were all disintegrating (the fill valve seal, flush valve tank seal and the two tank washer seals on the bolts that secure the tank to the bowl ). After finding the one toilet leaking, I immediately went and inspected all of the 4 remaining toilets and unfortunately found each of the others in the same condition, one of them was actually started leaking also, just not to the extent of the first one. I now have to replace all 5 toilets internal components (fill valves, flush valves and mounting bolts) because of using these tables. If we were out of town and this toilet started leaking and the fill valve continued to attempt to refill the tank this leak could have resulted in some very serious water damage. I would strongly recommend NOT using 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.

I have to use Clorox® Toilet Bowl Cleaner - with Bleach even with two of these in the toilet tank. The water only shows signs of the tablets functioning two out of the ten times that the toilet is flushed. Even when it is functioning, depending on the bacteria left behind by others, which we cannot always control, the tablets are ineffective at rinsing away congesting bacteria. I like to leave the toilet bowl cleaner on overnight to wake up with clear sinuses. I didn't know that the residue of other's toilet trips were keeping me up at night. I don't recommend this for the office, just because of the combination of a wide variety of people and different diets and behaviors associated what is considered edible, e.g. while one person would not eat meat that was defrosted five days ago, someone else might, and continue to eat it even if they did not like the way it tasted solely based on their experience of not having problems eating prolonged unfrozen meat in the past. The residue of one person's bacteria can literally clog up the sinuses of another while doing nothing to the person that released the bacteria, while the bacteria of the other person consuming/ eating fresher foods may make the other person just as ill. I would recommend more than one product for use in commercial settings rather than household. These tablets are a household product. I find the In-Tank Automatic Bowl Cleaner to be just as bad and dangerous because they are the color of mouthwashes and Windex.

I just started using these and boy is the bleach smell strong, almost way to strong. BUT it also caused brown streaks in my toilet bowl (not fecal either). I am now reading that these stains are from hard water which our city is really bad. Anyway, I am reading DON'T us bleach as it will make the rust stains worse. Which is interesting as I lived here 17 yrs and never had visible rust stains. And just with the use of 1 Clorox tablet I now have very noticable rust stains.

This is a nice price for your money

I love this toilet bowl clorox bleach. It make my bathroom smells clean!

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