The Kensington Gel Wrist Rest is very convenient in itself and serves its purpose fully. A variable amount of about 2 - 3 cm, it is also very versatile, just the height of 3 cm I felt for the work on an approximately 2 cm high laptop to be very comfortable. The only drawback is the unfortunately very unangehme, pungent plastic odor which distributes the joy of using this great se wrist rest.
