Query: WANTED it to work, but...

I really wanted this to work so I could use my old MS Natural Keyboard and Logitech Trackman Marble FX mouse with my new Dell Windows 7 pc, but it disappoints. When I type, the information from the keys to the computer goes astray frequently, leaving me with holes in the text where the words I entered should be. Or the text stalls and eventually catches up. Not good. I replaced this with the comparable Belkin product, which works perfectly. My advice: buy the Belkin and skip this product.
