great for small space, but needed tweaking


Easy to Install,Works Great,1.28gpf but flushes well.,Toto customer support was responsive.


Tank is way taller than necessary, but only style available in comfort height round bowl beige,Flush valve flapper tends to leak; needed tweaking

Other Thoughts:

Side mounted flush handle pulls flapper chain toward the front of tank, causing flapper to settle off center on flush valve orifice and leak into bowl, causing tank to refill every few minutes. I had to place a zip tie on the shaft between the back pivot ear of the flapper and the overflow pipe to keep the flapper from being pulled out of position. Since then it works flawlessly.
