This is a really great product with a power assist to help make flushing easier and clogs a thing of the past. I have had this toilet in my bathroom for about 5 years now. A friend and myself installed this after purchasing it from a local plumbing store and also researching results concerning it on line. I have also used the same model in various restaurants. The results are good and I have not had any clogs or backups since I installed it. The power assist still functions like the day I bought it and the overall quality as evidenced by 5 years of trouble free use appears to be quite high. The only possible catch may be the price as there are probably many folks who would object to paying 350.00 or more for this. I have not priced them recently but that was the cost about 5 years ago when it became necessary for me to seek out a replacement for the one I had. Despite the cost this is a very well made toilet with a power flush feature that works well.
