Happy Toilet Tablets Ultra Edition

They work really well.

After fitting the unit in the cistern, I'm on my second tablet; cleaning power is remarkable, no sign of the dreaded grey waterline. I do find that the bleach scent can be a little overpowering.

The canister unit specifically for the Kohler toilets is a super slick design, and works phenominally! It takes a minute or two to UPGRADE your flush system, and will undoubetedly save hours and dollars in cleaning chemicals and labor. I honestly noticed a difference with the first flush being quieter, but really saw a difference in the first couple of days in the bowl. 100% this guy recommended!

Love my clean toilet!

Happy Toilet Device was simple to install and does everything it’s advertised to do. Keeps my toilet extremely clean and smelling fresh!
