First off, I have to say the thing is filthy inside.
I know it is refurbished but, for decency's sake, can't they clean it up a bit before sending it out?
Now to bigger problems.
One of the three rollers, rolls nicely and makes no noise. A second roller makes some noise and the third one is really noisy and does not roll as well as the other ones.
Is this to be expected from a re-furbished trackball or am I getting a raw deal?
There is one specific direction in which, if I try to roll the ball, it tends to climb along on of the rollers and dislocates itself from its normal sitting position.
What is the proper way to lubricate this things? Would that solve the problem or should I send it back to the hell that spawned it?
Thanks.
