To basic function is to say that the gel wrists very soft and comfortable supporting, without which one really sinks in. The build quality shows no significant deficiencies, the only recognizable is that you can cut clean edges - but ultimately that's not really care for the overall picture.
Very pleasant I find the choice of material, who ever had a palm rest with fabric cover, knows how quickly it develops as a seed stove - through the plastic coating is in this palm rest but a simple wipe over it possible. The only downside that I previously look at this coating is that a very high frictional resistance is created - to move the hand to the keypad without lifting, for example not really possible - something that does not bother me, because I is not between keypad and main draw has to change keyboard or the like.
The weight of the palm rest is quite ideal - it is hard to slide around, but can be easily repositioned if necessary.
Light minus point is that the product has a slight odor after unpacking, I would assign from my experience and opinion of lay out the complex of plasticizers. Is only perceptible when one sniffs the nose directly to the support and can not be compared with some other products that smell really pushy for plasticizers and the smell dissipates after days. Accordingly, I would of the product for a long time discourage expose to direct sunlight, as it could be hard. For no real problem because the computer course is not exposed to the sun anyway.
Despite full marks because the desired function is very well satisfied.
