Terry, New to your site. Found it while searching for reviews on low flow toilets. Great site. We've decided to go with Toto Ultramax based on what we've read on your site. It looks like you recommend the Bio-Bidet products to use with the Ultramax. I was just wondering why you prefer the Bio-Bid to the Washlet. The Washlet is certainly quite a bit more expensive, but from a quality standpoint, is there much diference between the two product offerings? Thanks!
