Title: Great trackball, quality has slipped quite a bit
Review: I bought an early version of this model and used if just about every day for 10 years. A terrific device where all of the controls became natural to me quickly. I like that the long fingers operate the ball.2 years ago, my Trackman died. I bought a new one immediately. Since then, each has gone bad quickly. If my current one goes bad anytime soon, I will have to go find something else, looking for something not Logitech.A general note: as with any new and different HID, it will feel wrong and strange at first. Be patient, give it a a few weeks before you make your determination.
