SHISHISHUN 41A5034 G801CB-P Safety Sensor Kit Replacement Beam Eyes Compatible for Liftmaster/Sears/Chamberlain/Craftsman Garage Door Opener Operators Made After 1997 Universal (1 Door)

Garage door opener stopped working. These fixed it!!!

Junk, crap, I would rate less than one star if I could. Return if you can as it will not last. Spend the few extra $$$ and get the Sensor Kit from your garage door company. You will be better served in the long run.

these are great replacements . be sure to swap wires { not black stripe to black stripe or white to white } do black stripe to white . {opposite of what u assume to be normal } to get to work at least on my door . easy and good buy, unfortunately I did not need these as I found a chewed up part of wire directly from main unit on rafter above, chipmunk or squirrel chewed thru wire so I ran new wire and used my old sensors. I will buy these when needed .

I should not have to be a company's quality control. I wasted hours of my life trying to get these to work. This is garbage. It didn't work at all. Had to install the old ones. The lights don't even go on to show they are aligned no matter how close they are. Where is the quality control... oh yea we are the quality control, our time, our effort, and now I have to go return these. I feel like smashing them with a hammer.

These optical sensors were a great replacement for the original Liftmaster sensors. Fit exactly as the originals. Work well without any problems. Just as others have written, you must REVERSE the wire polarity when installing theses sensors. I would buy this item again.
