Ordered these 2 and neither one worked. One did not do anything and the other makes a clicking noise. I have these same plugs and they can be a pain to learn how to program them, but I know how these were just both bad and trying to return them has turned into a problem it is like the walmart program says I haven't ordered anything in months and this is simply wrong. They are having some kind of technical issues. As for the plugs, these work fine once programed, but they had similar ones at Lowes for black a 4 pack for 20 bucks, I think 5 a piece is about right, these are a little expensive now considering the technology is getting old.
