Review on Moen 2510 Posi Temp Balancing Connections by Chris Smotherman

I first saw that the plastic piece holding the valve only has 1 screw, but there were 3 more screw holes, so I figured this plastic piece needed 3 more screws. After looking more closely at the installation instructions, I saw that the piece of plastic needed to be used to align the direction of the valve. Apparently the plastic part was just there to show which way the valve should go and a screw was supposed to hold the two parts together. I wish there was a short insert explaining the parts included in the box and a purpose other than the installation guide, so giving 4 stars instead of 5.
