I was concerned about going from a 1.6 gpf to a 1.28. No worries! I've had it for a month now and there is no problem - it's actually better than the 1.6.gpf toilet I had. It's a lovely looking toilet and the perfect compact size for my power room. I wanted to try a comfort height toilet, but at 5'3" it's not super comfortable for me. So just be warned if you are on the short side, that may be an issue. But that was my intentional choice to try it. Overall, a really great toilet! Also, Wayfair delivery and communication alerts and notices and superior to any other provider I know.
