I'm a proud p00per which means I've used a lot of toilets in my day. This is by far the best residential toilet on the market. Doesn't clog and wash down is great. I have "put it to the test" and let me tell you this monster will suck the curtains off the windows! My 6'8" quarterback sized neighbor challenged me when I bragged about its performance. He intentionally tried to clog it without success. He liked it so much that he went home and ordered 3 for his house. In summary, it works as well as a pressure assisted toilet without the complexity and cost.
