Product review (4 stars): High Quality Receptacle
I have purchased many of these receptacles this year.  They are designed very well and is much better than the Universal receptacles which I also purchased to compare. The brass contacts (as pictured with black wires) where the surface burner element is plugged-into offers a much better and tighter fit than the universal receptacles.  In addition, the wire shielding is made of heat resistance fiberglass and not rubber/plastic.  I took one star away because of the missing screw which should have been included in the package (as pictured).
