BONTEC Small Ergonomics Desk Extender Tray, 20x9.5 Inch Table Mount Arm Rest Shelf, 90° Foldable Keyboard Tray Platform, Clamp on Computer Arm Rest for Desk, Suitable for Office Desks, Rustic Brown

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.

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.

💡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 anglesI 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.

Easy to set up, pretty stable and what I needed. However minor complaint is the rubber ring on the clamp. Under pressure and over time the ring slips off. So your rubber foot will be where it clamped, but the actual metal clamp part will detach and slide away from the foot and come off.So this comes with a periodic check to make sure the clamp isn't about to slip out. Great for resting arms but I wouldn't trust putting anything on it, or leaning on it at all.

Love these for desk extensions or displays

This thing is very handy. Gives me more desk space. Its very sturdy. Be aware of the brackets underneath. Took me a week to get used to them being there- I hit me knees on them a few times - it was very painful!

This didn't stay attached to my desk for more then 3 days before it has to be readjusted and retightened. Last time it fell off the screws came out of the bottom rendering this useless. It's just outside the return window too. What a waste of money

This thing is fantastic. The instructions for assembly, the protection of the pieces for shipping, labeling of the packaging/pieces, and the quality of the hardware, (the lever for folding it down is smooth and sturdy), was a pleasant surprise. The arm rests on my chair now meet the edge of my desk and I no longer have unsupported elbows!
