Qtronix Libra 90
« on: Wed, 20 May 2009, 18:09:00 »
I got this off of ebay for under 20 dollars shipped. Its a ps/2 with 9 pin serial adaptor and from the looks of it is NIB.

I am not expecting much from this particular trackball but thought I would give it a shot. Initial impressions are that ball feel is relatively smooth and the mouse has 3 buttons. Others here have mentioned that the overall quality is poor and that the device will end up failing.

Here are some pics:

Nice that it has metal rollers for bearings for the ball.  It's pretty funny the pcb is like half the size of the plastic.

I wasn't expecting it to have metal rollers. I think that is a good design though. Can't imagine them wearing out. The mouse is fairly large, actually its as big as the kensington expert.
