I installed the Compact Cadet 3 ,1Piece toilet yesterday. I used a regular wax ring, It can fit in small spaces which is great. It only uses 1.28 Gal. per flush, yet it has a powerful flush. It comes with a 5 year warranty. 16 1/2 inch seat height .It has the Ever Clean System to help fight stains. Single flush elongated toilet with the self slow closing lid. My kids use this bathroom and they find it easy to flush and use. So over all My wife and I are very happy with this toilet. One piece toilets are one less problem for leaks and for germs to collect.
