The best wrist rest I've used.
Size: Compact, Pattern Name: Keyboard
It has just the right balance of firmness and softness. The cooling gel does keep it cool. It is durable. Its rubber grip holds it firmly on my desktop. If I need another one, I will purchase this product.

It's fantastic. It's just not quite perfect.
Color: Black, Size: Full Size
Update after almost 2 years of ownership:
I've gotten very used the the height of the full height keyboard wrist rest. I can't go back to a smaller one. It's super comfortable. I bought a second one for work and 2 mouse wrist rests to go along. All of them are built fantastically. They clean easily. If something happened to one of the ones I already have, I would come straight back here to buy another of the same one. On point #2 in my original review below, I still wish the edges weren't tapered so much, but I have gotten used to it. I gave in and offset the wrist rest from the keyboard. Not ideal, but it gets the job done.
Bottom line: would recommend any time.
Original review:
The build quality is good. The fabric is nice and soft. The bottom keeps it from sliding. It seems great, overall. I have only 2 problems with this thing:
1. It's too thick. I should have gone with the thinner one. Maybe it'll wear out a bit and my hands will lower into a position with which I'm more comfortable.
2. The left and right sides taper off. It's fine that the front and back do, but having the sides tapered means that if I center this along the bottom of my keyboard and rest my hands to type, my left hand is partially sloping off to the left side, off of the rest. Obviously this is easily fixed by sliding the rest to the left of center, but I've got a compulsion about things lining up and this really really digs into my brain badly.

By about last year I started looking at more pricey wristpads like the leather wrapped ducky and several other imitations online
Color: Black, Size: Full Size, Color: Black, Size: Full Size
I've been using Grifiti wristpads for a few years now at home and work. I buy a replacement every 6/9 months due to them getting absolutely filthy and having the top fabric falling apart. By about last year I started looking at more pricey wristpads like the leather wrapped ducky and several other imitations online. I decided to wait and at one point heard of Glorious although I was on a new set of Grifiti's so didn't think a lot of it.
So the time came for new pads (once again!) and when I was checking for alternatives to the Grifiti (and the Leather from EliteKeyboards, Ducky, Filco, and other wristpads -- sheesh, I'd think I was talking keyboards there with names). Then I came across the Glorious and recalled its a higher quality wristpad so I decided to order a full and compact to use at work. Definitely very happy with them so far and by 6 months and a year then I'll see how they hold out.
Pros:
* Cushion-y soft great for resting and supporting wrists, hands, or an arm on
* Firm without being too hard or soft
* Cloth wrapped so they're not going to wear apart like a Grifiti
* Cloth is sewed to the base and not glued by inspection
* Doesn't slide, there's a textured non-slick rubber on the bottom. Great on my work desk!
* Good price, the leather imitation glued to a base starts at $30+ dollars and they go up to $70
Cons:
* None so far!
I'll be buying 1 more for home use in a month as im using both full and compact at work. The compact size matches up well with my mouse pad there although you may want to measure if you do this. May Gaben be with you!

Overall great
Color: Black, Size: Mouse Wrist Pad
All positive things to say except one mildly negative comment which is also personal preference.
Positives
1. Made well, doesn't fall apart or tear at the seams.
2. Perfect size for a mouse wrist rest
3. Comfortable for average duration usage, 2-5 hours
4. Simple yet elegant design, nothing over the top or "gamery" (It is a freakin wrist rest folks, it looks good and works)
5. Non slip rubber does keep it from sliding around the majority of times on the majority of surfaces such as glass and metal however on a slick laminate I find it still slides about a bit. It works well but when they look to the future perhaps an eval on this would help.
Negatives (Take with a grain of salt as I suffer from both Arthritis and Carpal Tunnel from 20 years of long duration PC use)
1. Too firm and not contoured to cradle your wrist. Because of this I find for my use (12-16 hours daily as I work and play on PC) it still causes fatigue and eventual pain. I would prefer the material cradle my wrist either by adding additional depth to the support material while softening it or again have a contoured shape.
Overall this works incredibly well and for somebody who put a ton of effort and money in the aesthetics of my PC master race set up with RGB everywhere and whatnot, having a simple and good looking wrist rest goes a long way to add to the look without detracting from any other element as those other "Gamer" wrist rests do. I love the thing and it is the best I have found however for my personal situation with wrist injuries I would love this company to produce one focused on fatigue prevention for those of folks with common PC use conditions.
