Bests & Worsts Reviews from Amazon

This is a terrible product and you should stay away from it. I bought it in March but did not install it until May. It is now June, just one month later. It is already leaking at the valve in the handle. How can that be? A total waste of money. Amazon says I cannot return it because the window closed. Really Amazon? Amazon, please help me out here. At the very least you should stop recommending the product.
