The Logitech G5 Laser Mouse has a distinctive feel to it thanks to the adjustable weight system implemented with a cartridge. There is a Battlefield 2142 version of the mouse designed with BF 2142 in mind for $10 more. The negatives of this mouse are the lack of a left-handed version (the shape and feel of the mouse is not geared towards the lefties.) The bottom line on the Logitech G5 Laser Mouse is that it is a great mouse for First Person Shooters and a good mouse for those wanting a more solid feel to their mice. I give it a solid Gold Award as it is one of the best gaming mice on the market today.
