Review on Eastman 10809LF Angle Stop Valve by Dwayne Quarles

I ordered 2 of these 1/2 x 3/8 check valves, the size says on the box but when I measured it was 3/4 x 3/8 So I sent them back and ordered 2 more. I received them today and they are STILL the wrong size but the packaging says otherwise. So the box says one dimension, but the actual piece inside the box has a different dimension. Therefore I will send them back AGAIN at this point, but will not order them again. Obviously there is a problem.
