Mouse Bridge is too Large
This is a good concept because the mouse bridge is low to the keyboard, and helps keep the wrists more neutral than a traditional mouse bridge.  Unfortunately, it is way to big for the newer standard PC keyboards, and there is very little space available on newer keyboards to place the feet of the bridge.  I took my mouse bridge to a local plastics shop to have it cut down to a smaller size;  it works OK now, but it still tips when I move toward the outer edges, and it covers the directional arrow keys.
