As far as people saying it has a nauseating smell, I don't agree with that. It does smell like bleach because it is bleach. It does keep the toilets clean and I have hard water and discoloration. Please note it is activated by the flushing of the toilet. The more flushing, the better. I have two toilets I don't use regularly so I go in there at least once a day to flush those. It beats using CLR in the toilets and it is cheaper. I'm a fan.

it keeps the toilet bowl clean and fresh smell scent after every flush. I usually maintain the bathroom once a week or twice depending how messy the boys get but with this, i don't have to do it frequent. What i like best is that it keeps the bowl from getting the ring it start to show once the week is up. thanks clorox, you really know how to help a mom out!

I have just moved into a house with hard water. Everything in my house was remodeled and I wanted to keep my toilets sparkling! The product removed the hard water stains and also RUINED the rubber flapper on BOTH of my toilets. I had to replace them both at the same exact time. Nowhere on the box does it warn about this!!!

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.

This stuff is awesome! I love products that I can easily set and forget and will do their job without any effort from me. I use this every 3 months or so to refresh my toilet bowl and ensure there is no build up. It is priced well and has good value. I recommend.

I have been using this superior product for years. This is one of those items you are willing to pay a little more for to get the most desirable results from. Having a clean commode is a must. I trust the cleanliness of mine to Clorox® in between cleanings. Each flush is a blast of cleanliness and freshness. My family and company always comment on the fresh smell and appearance of my restroom. I clean the entire room with the fine family of Clorox® products as they compliment each other in a way no other cleaners can!

Clorox toilet bowl keeps your bowl fresh, however, it's not good for your toilet bowl Flush Valve. So, far I had to replace two of my Flush Valve because the bleach or additives in the ingredients is not good for equipment. It's best to clean under your toiler bowl, rather than thinking you're getting clean and fresh odor from inside. I did the repair myself, but if you don't catch in time, your toilet will be doing a Ghost Flush and you will be hit with a large water bill from the constant running of water into the bowl.

I recently decided to try the Automatic Toilet Bowl Cleaner since I was unable to keep my toilet from staining and not from my own doing. I think it has something to do w the water. So far so good. I will continue to purchase this. Makes my weekly cleaning so much faster.

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.
