Review: Works like a champ - Looked different the original sensor but it was easy to install and works like a champ.
Review: Works well great - *Edit 1/10/2016* Has worked flawlessly. Has never failed to close due to light, cold or heat. I am very satisfied with the quality. *EDIT 8/5/2015* If I had read the directions I would have seen that the tabs bend with pliers. Now 5 star rating. The sensors can deal with a large amount of direct or indirect sunlight without any problems. I don't know why I didn't look for sensors sooner. I am very happy with this purchase. If you suspect dying sensors or problems with sunlight I would recommend trying these. *END EDIT* Works well with my opener, M-Line 4500. The old sensors would get blinded by the sun and not close unless I blocked the sunlight. The reason I knocked off one star is because they way the sensors attach to the mount is not as secure as I would think they should be. If I just touch it the sensor will swing like a door on its hinge. The mount is secure on the wall and steady, its just the sensor unit that moves. I used some tape to hold it in place, minor inconvenience but I don't like the idea that a bump could potentially knock the sensor off and break it.

### ⭐⭐⭐⭐⭐ Works Like a Champ!
*by D***E on April 25, 2015*

This fixed my Marantec Garage Door Unit like a champ! This was my first ever electrical project and it was simple. The sensors connected flawlessly. I didn't even need to get them in perfect alignment for the garage door to open and close again properly. This saved me at least the $150 cost that one company I called wanted to repair it and probably the $250 I would have spent to go ahead and replace the whole unit with a new Chamberlain. My only complaint was that the directions didn't really tell me how to splice the wires from the old sensors to the new, but a simple Youtube video and some common sense was all I needed to figure that out. Additionally, having had the old eye sensors, this now fixes the problem I had earlier with the garage door not closing twice a day due to the sun hitting it in a particular angle at those times. If you've got the old sensors buy these and replace the old ones. They are so much better and worth it.
