## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect fit! Fast delivery!
*by P***G on January 19, 2025*

I am very pleased with this purchase. Product photos and dimensions were accurate. The thickness overall, including the ribbing and molded edges, all seem to be top quality. The cover was protectively sealed in clear plastic so I am confident it was a brand new item, not recycled. The only thing I noticed was that the specification details as shown on the Amazon listing showed the wrong length of 20", but the product title correctly showed 48" and the width, depth and curved shape of the cover were all correct, so I placed the order. I'm glad I did. It's perfect!I would have welcomed a bit of instruction either sent with the product or accessible from the product's listing page that shows exactly how to install the cover. A 48" cover is inherently somewhat unwieldy. It requires holding one edge in place and applying pressure to the other edge to pop it in place. It is not easy to do across the entire the 48" cover at once.I didn't know which edge to put in place first or where to start applying pressure or how hard to push. I didn't want to crack or break the cover by doing it incorrectly. I ended up going on YouTube to find a video of another under cabinet lighting installation that showed exactly how to pop a similar cover in place.I learned that the flat edge goes in first. Then, you have to hold the cover in place and apply just enough pressure along the shorter curved edge to push the lip into place so that the grove fits into the edge of the fixture. Tricky but doable. Once I knew exactly how to do it, I wasn't worried that I might break it. I was able to install the cover myself within a minute with just a few attempts.

### ⭐⭐⭐⭐⭐ Would buy again and again!
*by S***R on July 31, 2025*

Very happy with the cover it fit perfectly good quality, dirty. I’m sure it’ll last for a while.

### ⭐⭐⭐⭐⭐ Perfect fit
*by P***F on June 8, 2025*

Since I did not know the manufacturer of my under counter fluorescent light, I went by the measurements from the old lens, and it fit the measurements of this lens. When I got it in, was surprised that it was a perfect fit in both the size and snap in tabs. This was a much-needed replacement lens since the old one kept falling out due to the florescent bulb heat slightly deforming and hardening the old lens. I have other lights similar to this one, and I'll be buying this lens again.
