Logitech Anywhere Mouse M905

Mouse...Mice...Mickey Mouse...? Why is it called a mouse when it's just a pointing device? I don't know, and I guess I won't discuss it here.
What I want to share here is a new computer mouse. It's from Logitech®.

What's so special about it?
It can be used on transparent surface!
What's transparent surface?
It can be referred to as glass surface.
Yes, this mouse can be used on glass coffee table without a need for opaque surface mouse pad.
It's now using a new optical sensor technology. Logitech® calls it Logitech® Darkfield Laser Tracking™.
So, now, this mouse is virtually applicable on any surface, regardless of it's opacity and transparency.
It's introduced as Logitech® Anywhere Mouse M905.

Its features include Wireless (RF) connected, programmable buttons, with 2 side integrated thumb buttons. 
(Note: it's stated however that the glass surface has to be minimm 4mm in thickness)
