Gotta agree about how pleased I am with the Acquia. Comfy (love the ADA height), flushes incredibly well, and is usually clean (although I keep a small brush set next to each toilet just in case). We've had them since February and have them in 2 bathrooms -- master and hall used by a teen. ONCE in all this time I had to flush a 2nd time -- and that's using the .9 gal -- twice with this is still waaaay less water than the multiple times I had to flush with the old toilets. We bought them just before our water district's voucher program ended -- saved $165 PER TOILET (we saved only $75 on the Toto Ultramax we needed for the powder room due to counter height restrictions -- otherwise would have used another Acquia). Love, love, love these toilets (and love confounding guests, LOL). Only complaint about the slow close seat involves "husband training" -- if he leaves it open, I need to wait for it to slowly close before I can use it.....he needs to be retrained, LOL.
