Product review (5 stars): Great! Quick! Cheap! NICE!
100% flawless installation-transition from my 4-prong dryer-cord.  I recently moved into an older home with a 3-prong outlet and I had to install this quickly to get my dryer going alongside my washer.

5-stars as it worked great--and it was cheap.  Saved me a 30-minute drive into town to buy one that would have cost me 2 to 3 times more.
