Lately I've been more interested in finding different ways to help the environment and saving money. You get a good feeling from being able to help save the environment and yet at the same time, able to save some money. So I'm always looking for a new way to do that even if it's just something small (cause every lil' bit helps).
According to the website it helps you save water and money everytime you take a shower. Everyone lets the water run while it warms up and what this does is once it detects that the water is hot enough, it'll show down the flow until you get in (or are ready to get in) and then you push a button to start the flow again. It can save you over $75 a year in wasted water costs.
I think I might buy one to test out and then post a review about it later. It sells for $39.95 and it should pay for itself within a few months.
