Query: Great unit except for the cheap handle/nob

I have ownded this item for 4 years. My parents had a similar device, though a different brand, and we fell in love with it. I bought this one hoping for the same quality, but was disappointed. While the tank and fittings have been fine, we have had trouble with the turn knob from the date of purchase. It doesn't sit tightly on the unit, spins freely without turning on the water sometime, and just has a cheap look and feel to it. Even when it does work, I just don't like the design. Since it is somewhat loose, you can't really predict which way to turn it to get the maximum water flow, and you have to play with it back and forth to finally get it going. I can't recommend this product, and would suggest you get a different brand.
