Great except for the bottom
Size: Keyboard Wrist Rest (Pack of 1), Style: Slim
Kensington stuff is always good. I’ve been using it for over two decades.
This wrist rest seemed like the best choice for my Apple Magic Keyboard. And it probably is.
My complaint is the bottom. It’s made with the assumption you want it in a fixed location on your desk, so the underside is sticky. On the other hand, if you don’t want to leave it stationary, the white backing paper is too slippery. I’d have MUCH preferred a textured rubber underside that helps it stay in place than this.
Also, it’s really really black. If you have dandruff, you’re going to notice it falling on here.

Desk Hoteling: Portable Comfort
Size: Keyboard Wrist Rest (Pack of 1), Style: Slim & Compact
New to the desk hoteling scene, I’ve had to find easily transportable ways to increase my comfort level. This has survived multiple backpack edits, which says a ton about this little wrist rest. I love that it is not cloth so I can wipe it down at the end of the day, but it doesn’t stick to your skin. It is the perfect size and thickness for my use. It wasn’t cheap, but it is holding up very well even with the constant travel. This is worth the extra bulk in the laptop backpack.

Quality Product, Definitely Recommend
Size: 17.2"L x 3.15"W x 0.78"H, Color: Black Walnut, Size: 17.2"L x 3.15"W x 0.78"H, Color: Black Walnut
Looks and feels great. Amazingly smooth, and well-crafted. It fits the length of my keyboard, and has quality grippers on the base to prevent sliding. Was actually really pleased with it.

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.
