Anyone else familiar with these products? http://www.a4tech.com/en/product1.asp?CID=102&SCID=131 I love my X-750F mouse ..check em out! 3 X Fire buttons, fans in mouses, different led colours for different sensitivitys, full laser engines etc..i had MX-518 earlier but it broke down..sooo i managed to find one of these for pretty low price..and gotta say i think my next mouse will also be a4tech..maybe underground products BUT they are cheap for what they have to offer..i think outlooks are pretty sleek too..try one if u have a chance! Gaming mouse with fan charged with 2500 dpi laser engine is pretty pwnage. It scored very good points and guys liked it in one finnish OC site review. Tell me if u have had any experiences or such with a4tech stuff.
