Product review (3 stars): It is useful for camping
I bought this product thinking it would save water and money.

It does both of those things. But. A honest break down of this mechanism
Is. A bucked that you can spin with a handle and drain with a sligh vacuum pressure. It is useful for camping. But not useful if you have runnin water, a bath tub, a sink, or a bucket that you can drain.

I am not trying to push you away from the product. But help you understand that you can achieve this goal with what you have at home. And if not.m, BUY IT.
