The only problem with this design is getting it to stay in one place.  It has a tendency to slide on the keyboard tray we have which is clear coated oak plywood, commercially finished.  I am tempted to test using rubber glue under it or if absolutely necessary contact cement.  Of course if it is too secured in place the problem will be removing it for replacement later on.  Most mouse pads I have seen have a larger surface area for the mouse to move on, but so far that has not seemed to be a noticeable problem in use.
