Logitech Marble Mouse Problems

Background: I have used trackballs for many years.  My favorite of all time was the Kensington TurboMouse: I still have 4 of them, but they are all breaking, not working so well.  I have reluctantly been forced to use the Kensington Expert Mouse, and have used others in the past.  (Reluctantly, because I find the newer Expert Mouse and SlimBlade and others just don't work so well.  I suppose that there must be a reason why Kensington discontinued the TurboBall. Probably reviews such as http://www1.epinions.com/review/cmhd-MousingDevices-All-Kensington_TurboBall/content_43841326724).

A few weeks ago I decided to try a Logitech Marble Mouse.  For several reasons, including:

a) it is available in more stores.

b) it is smaller than the Expert Mouse, and could fit on a small keyboard tray


I was concerned that it did not have a scroll wheel, like the Kensingtons.  And, that has been a pain. 

But, there is a much more important problem:  this trackball works for a while, and then stops.  Replugging the USB doesn't help.  The only thing that seems to help is rebooting, and/or reinstalling the Logitech software.

Like I said, I have used a wide variety of trackballs, manly Kensingtons but also others.  I have NEVER had these sporadic failures and silences with any other device. Heck, it should not be necessary to install software at all, should it?  I normally don't have to for other devices.

Buyer beware.  I can't recommend this Logitech Marble Mouse trackball.   I am going to go to the store and buy another Kensington Expert Mouse this evening or tomorrow.
