Review: Easy install & operation. Everything i expected. - Loving this desk extender so far. I've been using it for a couple weeks to add more room for my computer desk. I use it to hold my keyboard, wrist rest, and Streamdeck. These are my observations: - There are 6 screws you have to put in to secure the shelf to the hardware; 3 on each side. Easy installation. - This wood shelf has these metal studs already built-in where screws go into, which means the screws don't actually dig into the wood and so you don't risk stripping the wood. It's a sign of a quality install. - Once mounted on your desk, the shelf surface is level with the top of the steel bracket. It would've been better if the shelf was level to the desk surface that it's mounted on. The difference is only about 2mm though. This is my only nitpick. - I bought the faux-carbon fiber version, which doesn't look like real carbon fiber but still looks good overall in my opinion. - The hardware feels very solid and the shelf lies perfectly flat when extended. - The latches are very easy to operate and you have to operate both latches at the same time to put the shelf back down. This means that even if one latch fails, it will still hold up. - When you fold the shelf back up, the latches will auto-lock into place which gives off a very satisfying and reassuring click. - I have a very thin solid-steel desk that's only about 2-3mm thick and I was able to mount it easily without having to add many spacers.
Review: Great Product Engineered well - An outstanding product easy to install (although I had to make adjustment to where the mechanism attached due to a cornice on my desk that I missed measured), great looks it matches my desk finish, added more functionality to my desk and very reasonably priced. A very fun project that is extremely useful.

### ⭐⭐⭐⭐⭐ Back Pain Gone! Fixed My Posture & Note-Taking Struggles. **Read for tips on installation**
*by M***3 on August 7, 2025*

💡Installation tip: The Anker clamp is adjustable. If it doesn't fit under your desk lip at first, just loosen and reposition the screws to lower the anchor arm (anchor clamp)—I’ve included a photo of the area I mean. Once I did that, it fit perfectly. I truly don’t understand why this has a high return rate—this desk extender is awesome once you know how to install it correctly. I mainly use it as a dedicated spot for my notepad, and it has completely changed my work setup for the better. Before this, I had to move my mouse or awkwardly bend over the far side of my desk just to jot something down. That constant twisting and hunching was wrecking my back. Now, I can take notes comfortably without shifting anything—and my posture has noticeably improved. 🎯 A few more reasons I love it: ✅ The surface is durable and waterproof — no peeling, no bubbling, no chipping ✅ No damage to your desk — attaches with sturdy C-clamps, no drilling ✅ Spacious and strong — easily holds my notepad, mouse, or tablet ✅ Folds away neatly when not in use ✅ Huge ergonomic relief — no more back pain from bad angles I actually bought a small side table before this one, and it bubbled up after a single water spill—so frustrating! This desk tray, on the other hand, wipes clean easily and shows no signs of wear, even after everyday use. Bottom line: This is one of the best ergonomic upgrades I’ve made to my desk. If you’re thinking of returning it because the clamp doesn’t fit—don’t! Adjust the screws and give it a real chance. It's affordable, durable, and way more useful than I expected.
