I had the original TrackMan Wheel mouse (with a cord) and loved it.  I regretted letting my mother-in-law have it the very second I agreed to it.

I purchased this one as a replacement once I realised I didn't like a normal mouse any more.  Plus I purchased a laptop and thought the cordless would be handy.

This model works excellent and is great for use at home with a desktop computer.  Unfortunately, it doesnt mention in the description or photo that the receiver which plugs into the USB port is HUGE, its almsost as big as the mouse itself.  The size of the receiver and length of cord that comes with it is the same as having a mouse, completely defeating most of the purpose of a cordless mouse.  It is too bulky to carry around and setup on my laptop like I had hoped.  The receiver is much larger than the ones that come on the other cordless mice I have seen.

If you like the TrackMan Wheel I highly recomend this one, it is top quality and functions flawlessly, as long as you don't want to rely on portability.  If you plan on carrying it with your laptop, I would recomend a different cordless mouse.
