Pros: Product is water usage efficient, as promised.
Cons: Design flaw causes tank leak.
When toilet is flushed, the water tub tips forward dumping water to front bottom of tank. Water then splashes to back of tank, up the back wall of the tank and out the two tank rear lip indentations onto the wall behind the tank and down the outside of the tank onto the floor. Product needs to go back to drawing board to correct tank splash/leak problem. Retro-fit corrective solution also needs to be created and provided to current owners, if product is to become more than just a pretty throne.
