Kaboom Church And Dwight 35113" Scrub Free Toilet Cleaning System (Pack of 2)

Boy does it work. This cleaning system removed black mold appearing at the water line inside our toilet bowls. Finding an automatic toilet bowl cleaner that didn't give off heavy chlorine fumes has been a real challenge. We try to use all natural cleaning agents whenever possible. After reading many product reviews for various automatic toilet bowl cleaning systems, I decided to give the Kaboom Scrub Free Toilet Cleaning System a try. Installation was easy and took about five minutes per toilet.After cleaning the toilet bowls, I installed the Kaboom systems. Ten days later those toilet bowls are still pristine clean. No mold build-up anywhere. There is only a very faint smell of bromine(?) from the Kaboom system, which has not been a problem.It's now going on three weeks and our toilet bowls are still spotlessly clean.

Works great!If your tank lid wobbles due to this, make an offset with a coat hangerSee photo

These are amazing little contraptions! I dont use the Kaboom tabs I use bromine tablets from Clorox made for spa's, Much cheaper and do a great job. I have had to use small round o-rings rolled over the rubber tube ends to keep it connected to the nipples. After about a year of use the rubber tube loosened and was spraying water alover.

Most likely my fault for not reading the description closer, but these would not work in my toilets. I bought four of them for all the bathrooms in my house. I ended up giving them away and was disappointed that I didn’t understand how they were going to work in the installation process earlier. They may or may not work well; I don’t know. I never got that far.

This is the best and easiest toilet bowl cleaner I have ever used or seen.It does have a chlorine odor but it's a clean odor.Less that five minutes to install.UPDATE; I bought this eleven months ago and I still think they are the best !! BUT, it has started leaking at the end seals and had to be replaced. It appears the chlorine broke down the adhesive that holds the plastic ends together. You have to check them.
