I really like the quality, but I have to admit that the "double cyclone" isn't as impressive as the videos portray. I originally bought this particular model because it was listed as "best" on the compatibility chart for my Brondell Bidet Seat (which I LOVE). The seat mounting hole to tank set-back required is 1-1/2" which it has, but the surface isn't perfectly flat like the seat requires. Other than those issues, I fine the style and function very acceptable. I will probably buy two more for my other bathrooms for continuity's sake.
