Steve: Excellent works on old model and no problem issues. ⭐⭐⭐⭐⭐

Nicholas T. Graham: My sensors on my garage door finally became too frustrating to deal with anymore. I bought the right year replacement and the install took me 10 min. I feel like I did something wrong, it was so easy. The wire connectors were amazingly easy to use. Now my garage door works like a charm.

Webb: My almost 30 year old sensor stopped working and the door would no longer work properly. I ordered these and replacement was very easy and requires no fancy tools and includes a wire crimp to make connection to your existing wiring a snap.

patrina coverdell: These were very easy to install and they ended working great. I do recommend this product. I’m so happy to have my garage doors working again.

Amazon Customer: OK, these are for older Lift Master garage door openers. I find the quality very good.

Karen: I ordered a replacement sensor for a Craftsman door that was made in 1996 so I required the part that was shown in the picture. Instead I was sent a sensor for a door made after 1997 that was labelled as 41a4373a. I thought it was just a mix up so I returned it and reordered only to receive the same thing.

SG 1: I cant give this the product a good or bad review since what they shipped was not what they showed. I have a 1996 Craftsman 1/2 HP opener (Canadian model). My sensors are larger and have a through bolt for mounting. They sent a newer model that has a different mounting system. My brackets would not work and the new ones don't come with brackets. So I bought here on amazon a new style set with brackets made by Chamberlain for much cheaper then these.

Gary : Easy to install and lots of new wire to replace the broken wire at the bottom of the rails.
