Seems very cheap. Can't see much information online. Is it Mac compatible?
Any reviews?

OK, so I realise this is not a popular thread, however it was a case of the blue cube PS/2 adapter not working on the Libre 90. Today I got a Belkin USB dual PS/2 adapter and immediately the trackball jumped into life.
Just a few things now, is there a programme similar to Karabiner, for pointing devices?
I am unable to scroll on this device, but other than that, for the £5.80 that I paid, including postage! I am delighted. It metal rollers and as far as trackballs go, (this is my first) I am happy with its looks. Its well made and feels nice. The ball itself makes a nice reassuring sound when moving, and the Mac preferences let me tweak some things, but not control the buttons. This device has three buttons.
With best,
Yours hopefully

Ah never.... this forum is a great source of knowledge, usually! 
For any UK members with an eBay account, this seller has one more, I'd recommend it, if you are in the market for a cheap but excellent trackpad. Naturally I'll do a review in a few weeks time, its too early to tell just yet.
