Alright. Cut not clean
Color: Red
Looks nice, but the V cut is not the best. One of the end does not come out clean

Size: 100% Standard, Size: 100% Standard
A nice leather cushion that fits perfect with keyboard. Definitely made a difference in wrist comfort. Good price and well made. A simple item done right and happy with purchase. I was hesitant as it said a frequently returned item. I dont see reason to return. Im guessing most people didnt get the correct size.

Simple and Straightforward Wrist Rest
Size: 60% Compact
There's not much to write home about here other than it suits the purposes I purchased it for.
This accompanies my K629-RGB Redragon keyboard. It lines up pretty well with the keyboard, and the rest itself makes a nice incline between my desk surface and the keyboard. The padding isn't too plush and is pretty good at providing wrist support. It's also been very good at holding its shape despite the pressure that my wrists have put in the same spot over the last few months; the padding is even across the entire wrist rest as a result. I've noticed that my hand doesn't cramp as much when typing for long periods of time with this rest, so it's doing exactly what I would expect for the ergonomics of my keyboard.
One downside is that it's prone to develop sweat marks where you rest your palms. It can't really be wiped away, given that it gets absorbed over time. I would say that if you are concerned with the appearance of the product, you may want to look into a plastic rest instead. I personally don't find this to be much of an issue since the pad is black, and you can only see the marks at certain angles, but I can understand if that's a dealbreaker for some. Otherwise, the rest of the pad is easily cleaned. I usually use a handheld vacuum to tackle dust and crumbs that stick onto the sides and bottom of the pad.
Overall, I would recommend this to anyone who has a compact keyboard without a built-in hand rest. The pad is perfectly sized for my needs and provides the support that I need for my work. If you're hesitant about dealing with a product that may stain, look into plastic wrist rests instead.
