So for the wrists, the keyboard tray wrist from the first second was great to! Immediately the wrist pain was gone.
The product has unfortunately my hands quite stained blue ... Despite scrub the tray has 1 Week (daily use) lasted until they no longer colored. Maybe it's in the other color options not so, but in the blue variant was to clearly notice anyway. Therefore, the product of me did not get all the stars.

PS The palm rest for the mouse is also great! I have it. For more than 2 years and it still looks like new In addition, I can not remember here blue fingers ...
