Instructions

When my garage door stopped working I had a guy come out who diagnosed it as a bad motor and the entire system had to be replaced. $550! I was pretty sure it was the sensor so I bought this, installed it, and voila!

Saved me $500

walmart.com

Our Lift master garage door sensors were in need of replacement. The Lift master is mid 1990s and they do not make the sensors anymore.  After researching options, the least expensive route was to purchase these sensors. 
They arrived in two days. (Company is located in Connecticut. Shipped a few states away in the same time zone.)
Parts arrived in great shape.  Two sensors, two brackets, four wood screws, and four screws to attach sensors to the brackets.
The only issue I had was that the brackets were not long enough to clear the bottom of the garage door hardware. My garage doors are older so it may not be an issue for others. They do not make bracket extensions, so I had to add a block of wood to allow clearance.
After mounting the brackets and wiring the sensors, I aligned them.  (The sender sensor has a constant red light and the receiver's red light will illuminate when they are aligned.)
Garage door worked like it was supposed to.
I would recommend this product if your sensors are not working properly.

Works great on my Stanley/Whistler Model ST401. A07.... Sent out Priority mail so it arrived sooner than expected. Per the instructions it didn't take long to install.

Garage door is back working ....

Good product and but instructions are not that good. I had to spend lot of time online to figure out how to use this product

Digi Code for Stanley

satisfied

Price was right but upon receiving I found the wiring instructions to be on insufficient side and in fact, I was never able to match the connection points on these sensors to the wiring on my existing (malfunctioning) sensors which they were allegedly supposed to be compatible with.  These sensors probably work fine if your "sending" and "receiving" sensors only use two wires each as these replacements only use two connection points/posts each.  My existing wiring had four wires on the "receiver" end.  Following the minimal included instructions were no help in resolving this issue.  Fortunately, I got my old sensors working again.

Somewhat Disappointed

It works but only after putting them about 2 feet apart from each other. Something seemed off about the sensors and they couldnt connect from regular garage door distance (one stall length). Professionally installed as well so everything was tried but would not work the way it is supposed to do.
