This toilet will not clog. I purchased a condo with 2 bathrooms and replaced both toilets with the Cadet 3, right height, round bowl toilets. Simply stated, this is the best toilet I have ever owned. Very easy to install, and very "clean" looking with the hidden trap. I have had these toilets for nearly a year, and have had no problems whatsoever with them. Liquid waste can be removed with a simple flush, and solid waste can be removed with a "serious" flush by simply holding the handle down. Great product, and I'd highly recommend it.
