Love these for our toilets

Drop em in the back bowl and they do the work.

Necessary in my house, the only thing that keeps the mold from growing in our toilets.

Quickly degrades the flapper inside the tank

These really keep the toilet bowl clean and fresh.

Works, keeps toliet clean

They work very well,i will buy again

Works nicely and keeps toilet fresh and easy to use

They stop that ring that forms in the toilet. Much better than scraping it out.

Works really good smell clean with every flush
