When the disc has disolved, it becomes apparent. The toilet needs more frequently and deeper cleaning. We have hard water. Perhaps this isn't true for those with soft water.

I love the smell of bleach every time I flush the toilet. To me it signals clean. I dont ever get that nasty ring around my toilet bowl and it helps with keeping odors down in the bathroom. Theyre great!

I can't stand a dirty toilet and this product makes sure my toilet stays cleaner without the work! I love knowing this product works with every flush to keep my house cleaner and more sanitary.

We have hard water, so it is hard to keep the build-up out of the bowl. The Clorox bleach tabs help keep the bowl sparkling clean even between deep cleanings!

Using the Clorox Automatic Toilet Bowl Cleaner (Bleach) has made it so much easier to keep the toilet bowl smelling fresh, staying clean, and avoiding that yucky ring around the bowl.

Why are these even allowed to be sold? The first tablet hadn't even fully dissolved when our toilet's valve stopped working. We have to replace the entire apparatus in the tank!

Product was damaged so a chunk that had detached fell off hit my bare leg leaving powder on it and it was on the floor. Would not vacuum up hoping mopping helped but I’m curious this touched my skin. Reeks of bleach, can barely go into the bathroom.

This is my all time FAVORITE toilet bowl cleaner. I don't have to worry about rings in the toilet when I have one of these bad boys in there. No worries...

IT DAMAGE EVERYTHING THAT IS PLASTIC I USED IT FOR ALMOST A YEAR WHEN WE NOTICED WATER LEAKS FROM OUR TOILETS MY HUSBAND HAD TO FIXED ALL THREE TOILETS IN OUR HOME EVER SINCE I STOPPED USING THIS PROBLEM STOPPED.

These Automatic bowl cleaners do an excellent job of keeping the bowl clean and fresh smelling in between scrubbings. I would recommend them to anyone!
