...works fine if it fits. I have units installed on two toilets and although the "lite" flush is just that, it works fine.
Didn't fit in my tank. Was too high.
Screw this crap. Remove your toilet tank and replace it with a 55gal. oil drum. You will then be able to flush medium size children if necessary.
I urinate in the tank to conserve water.
I uninate in the sink. It uses no water.
Poo do; pee don't.
Just don't pee or poo anymore. Mind over matter.
THE WATER CRISIS IS OVER. FLUSH ALL YOU WANT!
