High quality solid wood rest
Size: 14.4"L x 3.15"W x 0.78"H, Color: Black Walnut
This wrist rest is nicely finished and was well packed in high-density foam as well as a cardboard box that was wrapped very tightly in thick plastic. It's sanded very, very smooth and is made of beautiful solid walnut, with nonskid pads on the back. The branding is on the side that touches the keyboard, so it is not visible or obtrusive at all. My keyboard is 15.5 inches long, and the 14.4 inch rest looks great up against it. The 0.78" thickness is also very suitable for the thickness of my keyboard.
The product gets 5 stars because it is accurately represented and this is entirely down to personal preference, but something about this rest that I don't love is the degree of incline. I have my keyboard up on the kickstands, and the wrist rest that I already owned slopes pretty dramatically starting from the middle, so it follows the angle of the keyboard. The ZQL wrist rest is about 75% flat and then has a small slope that rounds off on the bottom edge.
Again, this is very much a personal thing; I just brought it up because it's something that people might not think too much about until they actually use it. I think this rest would be great for anyone with very large hands, or with a flat keyboard. It's taking a little getting used to for me, but I really enjoy the smoothness and obvious quality of the wood. A wrist rest is an ergonomic must when it comes to thicker keyboards.

Nice. I like that the wood feels cool to the touch

A nice little wooden wrist rest.
I would suggest not using it as a wrist rest, but use it more as a palm rest, because if you are having pain, putting more pressure on those wrist tendons is not gonna help.
Quality of the item is good. My biggest worry about wooden wrist rests is that they'll not be sanded well, or not smooth, and you'll get a sliver or catch your skin on a piece. Second biggest worry is that they will be slippery, and slide around the desk, or just be covered with a coating or finish that is sticky for human skin.
I'm happy to say, that this didn't have those issues. Mine is smooth, and made of dense wood. It doesn't feel cheap and made with hollow wood. There are no burs or slivers. It's not lacquered or sticky for your hands. It doesn't stain my hands when in use. And it has rubber feet to help grip, so it doesn't slide around.
One benefit to having a wood wrist rest, is that it stays "cool" to the touch longer than cloth or gel pads. But, at the same time, one heated, it takes longer to cool back down.
I've found that I quite like the cool sensation that is unique to wood.
I'm happy with it and the overall quality.

Great looking wrist rest but lacks strong grip
The walnut wood looks and feels great and gives my desk setup a more premium look. The dimensions are as described on the product page. I have no doubt this wrist rest will last a long time given how solid and well made it is.
The only downside is that it tends to move around a bit more than my old silicon wrist rest. The grip on the bottom isn’t as strong so I find myself readjusting it occasionally when gaming. Overall, recommended.

Very classy looking! Perfect height and length for TKL keyboards!
This wrist rest is the perfect height and length for my TKL keyboards! The wood is soft and smooth. It looks VERY classy compared to some of the wrist rests I've used in the past. The non-slip pads work great too.
The only thing I could find that was wrong is that the logo is upside down. It's not visible though because it's the edge that meets the keyboard so it's never seen. I find it endearing actually! Everything else is perfect, so I'd definitely recommend!

Classy look, but finish issue
This walnut wrist rest looks great on the desk—simple, solid, and much nicer than foam or gel options. It has a clean, polished style that pairs well with a keyboard, and the non-slip base keeps it from sliding around.
I wasn’t sure how I would like it compared to the soft cushy pad I used before, but it’s actually been pretty comfortable. The firmness gives steady support, and I haven’t found it too uncomfortable even after longer typing sessions.
The one drawback is a spot where the finish has worn or dissolved. It wasn’t there when I first got it, so I suspect the coating isn’t as durable as I’d hoped. It doesn’t affect how it feels in use, but it does stand out on an otherwise sharp-looking piece.
Overall, it’s a nice upgrade if you want a wooden wrist rest, just be aware the finish might not stay flawless over time.
