Recently bought a contour rollermouse to ease shoulder pain. It works reasonably well in mitigating those killer diagonal shoulder stretches (as you'd expect for nearly £200!) but most disappointing in that it doesn't provide adequate wrist support. There are cushions to left and right of the roller bar but nothing to support the wrist when actually using the roller bar and mouse keys - which is most of the time !! Therefore looks like I will now have to buy extra wrist supports - which makes this an even more expensive solution.
