Don't buy knockoffs
Had nothing but problems with cheap sensors, so I sprung for the OEM Chamberlain, and glad I did. Super easy install, fit correctly. Very bright lights to indicate alignment. No problems since!

Great new replacement!
As long as you have a compatible brand, these sensors will be a great option for anyone looking for new garage sensors or someone having difficulty with their old sensors. This will fit right in place of the old sensors with the included bracket that attaches to the garage railing. Crimp the new wires together and align the sensors, test your garage, and it's as simple as that!

Great delivery time!
I ordered this and received it in one day. OMG so fast and the product was terrific. If you have a garage door technician come out they will charge you 175.00 for the part only. It was 25.00 through Walmart.

The fact they had the name brand item available and at a reasonable price was a very appreciated surprise. The quality of the item was exactly what we needed to get our project done!

Good replacement sensors. No wire included tho.
Good replacement option for OEM reversing sensors. I would say better than the original, expect the kit did not include the expected replacement wire. IMO this should be included since wiring is often the culprit when your sensors stop working.

I don't know how Walmart does it, but the same product as you can find elsewhere but for half the price. This was easy to connect and easy to use. Very happy I found it on Walmart's website.
