Quick tip for future buyers from my experience of owning one of these:
The mouse wrist pad/supporter is to steep, hard or small to actually prevent the strain issues it is meant for. Instead of your desk pressing into your arm, the wrist pad will and the strain returns. The keyboard version, however does do its job fairly well.
Alternative to this drop:
If you're getting strain issues on the wrist of your "mouse arm", I'd first recommend getting a desk chair that can support your arms. Second, make sure your arm can lie flat on your desk. Both tips prevent one single pressure point from existing, thus preventing most common strain issues and making this drop partially unnecessary.
