Customers have negative opinions about the value and closure of the product. They say it's a stupid expensive piece of plasticized cardboard that's not worth the effort. Customers also mention that the door won't close on sunny days and that it intermittently stops when closing. Opinions are mixed on performance, ease of installation, and quality.

WOW, these work great to block the sun and let the garage door close every time. They are a little tricky to install, however it's not rocket science. All you need to do is look at the picture and fold it and install as it looks. I definitely recommend them.

Goes on quickly. Immediately fixed the issues with our garage door sensors being triggered by the winter Southern afternoon sun. The door sensors worked fine in Spring-Fall, but once the leaves were off of the trees the direct sun made closing the garage door a losing battle in the afternoon. Installed these guards in less than 5 minutes per side and had instant results. I haven't had the garage door sensor triggered by sunlight a single time since in several months.

1.0 out of 5 stars Doesn’t fit
Reviewed in the United States on October 24, 2023

These are waaaay too expensive and they didn’t even work on my sensors. As others have mentioned, the instructions are rubbish, but even after watching the 6:04 minute video, I couldn’t get the shields on my sensors. The tab that is supposed to slide into the clips can’t because my clips are welded. Just folding the shield into a "box" didn’t work either because if the one hole was lined up with the wingnut bolt and the other was lined up with the green light, the "box" didn’t even reach the sensor. I guess these horribly expensive pieces of plasticized cardboard aren’t compatible with my Liftmaster sensors.

It didn’t work, but that could be the angle of my house compared to the sun. The instructions that came with it were difficult, and I ended up having to watch a video on YouTube to figure out how to do it. I think it has the potential to work just not for my house.

4.0 out of 5 stars I got my garage door to close with the sun shining on the sensor, but needed to align the sensor
Reviewed in the United States on September 24, 2016
Verified Purchase
After a professional installation of a garage door and a Liftmaster opener in the morning, everything worked great until the afternoon when the sun hit the sensor with the green light and the door wouldn't close unless I held the wired controller's button down until it closed. After looking for solutions online, I tried the toilet paper roll trick. The roll didn't seem like a good solution since it didn't fit over the bracket securely. Furthermore, it didn't even solve my problem.

After a week of frustration, I decided for $9, I might as well try this and if this didn't work I was going to call the installer to switch the sides of the yellow and green sensors. It took an entire week to receive this thing.

After reading all of the reviews here, I knew to be wary of the instructions. I looked at them, looked at my sensors, and basically folded the thing into the needed rectangle WITHOUT pushing it into the bracket first. This made everything so much easier and really only took a minute to figure out. After installing both sides (I don't really think the yellow sensor needs one), it still didn't work. However, after installing the black cardboard, I had to adjust the sensor alignment. I noticed that the sensor didn't like up exactly and I couldn't mount the sensor securely to the bracket to get a good signal. I had to bend my bracket more so that the sensors aligned better and WOILA, the unit now closed with the sun shining on it.

I did not take the cardboard off to see if I really needed it. I give it only 4 stars because I had to tape the ends together so that it stays a rectangular shape. You would think that they could have that piece extend farther so that it also gets clamped together by the wing nut securing the sensor.

5.0 out of 5 stars Works great in the Arizona desert
Reviewed in the United States on August 16, 2015

Had to get a pair of these for my garage sensors, we live in the Phoenix AZ area. The desert afternoon sun shines right on the right sensor causing it to intermittently stop the door when closing when it's shining on it just right. So I installed these and not one problem since then these work great. Wish these were made out of a more durable plastic or metal. They seems to be made of a very lightweight honeycomb thin plastic (not cardboard). If you follow the directions you will not break or mess them up. Mine went on with any trouble in 5 minutes and look great. I decided to add a little glue to the top part to close the small gap on one of them once folded over. All I know is these do work and completely fixed my issue with the strong desert sun shining on the sensor in the afternoons.

UPDATE: It's now July 10 and we have not had one failure with this thing. The door has never missed closing. It seems crazy - it's basically a piece of cardboard. But take your time and look at the video at each step and it just plain works.

Unbelievable. Sun shines on our sensor about an hour and a half each morning. I followed one of the videos on how to fold it, pausing the video every couple of seconds to do the fold and realized it was easier to fold than it looked. Forget the instructions, use one of the videos. The tricky part is when you unscrew the wing nut to put it back over one of the holes because the sensor position will shift. You have to be sure it's lined back up perfectly. Whole thing probably took 10 minutes, from the time I started watching the video until I went out to the garage and installed it. Got its first test this morning with the sun blazing right on it and the door closed first time. You have to do it carefully and slowly and you'll need to make minor adjustments along the way but unless the sun is exactly straight on at the sensor it should work for you.
