The concept of the idea is really good but the product itself is difficult to use. Really it must be put at the bottom of the tub and correctly position the otherwise in the middle of the bath, he flees and leaves water from the wrong side. And even when I think I well dressed, half the time it starts to leak. So most of the time, I make no saving water because the tub is finally completely filled. Moreover, measure out the bottom of your bath, as this product does not fit all bath. Those that are too curved at the bottom do not allow the adhesion of suckers and, suddenly, the gearbox does not hold. Finally, this product is quite expensive if you consider the fact that once 2 it does not and does not hold water savings.
