What Customers Are Saying
The garage door sensors are generally easy to install and set up, with clear instructions and compatibility with various opener models. The bright LED indicator lights make it easy to confirm proper alignment and functioning. The sensors reliably detect obstacles and halt the door's movement, providing good safety. However, some customers experienced compatibility issues with certain opener brands, and the included mounting hardware was insufficient for some needs. Overall, the sensors offer easy installation and reliable performance, but compatibility should be verified before purchase.

Don't buy knockoffs
Would RecommendHad 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!

Product, who knows? Terrible online buy/delivery
Would RecommendBought online and had free delivery option from local Lowe's. Product delivery was obviously used: box seal was cut, box was crushed and dusty, parts missing from inside. Luckily I live two miles from Lowes, and they accepted the return with no problem. But why is this even on the shelf?
Residential garage door opener systems only
Would RecommendNice equipment but not for commercial liftmaster.

Missing Parts
Would RecommendI ordered these for curbside pickup. Went to install them right away and noticed that the box had obviously been opened. Find mounting bolts and wing nuts missing. Couldn't use the old ones as they were a different size. I had on hand a couple of long bolts and nuts that kind of worked. Not happy.

Lowes is the place to shop.
Would RecommendShopping at LOWES is usually easy as it was this time. The sales person took me to the area and I found what I needed at a fair price.

Worked Good
Would RecommendThe sensors replaced the ones I had installed with the door 25 years ago. Easy direct replacement no muss no fuss. Just snip the old wires and twist on the new ones.
