Query: Not A Shut Valve

This device is incorrectly named, because it doesn't shut off the water all the way. If it's to prevent cross-flow or to allow the hot water to flow slightly without wasting much water until it comes up to temp, then fine but the instructions don't imply either of this. Instead, the packaging clearly says it's a shut off valve. If water continues to trickle when the valve is in the off position, then you can't claim it to be a shut off valve. Just saying.My 2.5gpm shower head doesn't appear to be designed to work well with this valve. I thought it would be an inexpensive way at reducing the water use further with my shower head. I probably should have just spent the $75 for a Bricor shower head instead.
