Sold my Logitech MX700 (900Dpi) and ordered myself a Razer BoomSlang 2100dpi the other day, anyway, it arrived a few days ago and its bloody marvelous!! If you play FPS's online and you are playing at a high resolution you know that if you have a pretty crappy mouse its very difficult to aim at somebody far away because the crosshair skips pixels, buying one of these Boomers has completely solved that, if you so much as look at it, it moves its so sensitive. I was playing the UT2004 demo last night on an iGib server and i was getting almost 80% accuracy, its feels really comfortable in your hand, the weight is perfect and it has teflon mouse feet so it glides flawlessly over my Icemat, the "on-the-fly" mouse sensitity is the most brilliant thing ever imo, all you gotta do is hold down the thumb button and scroll the mouse up and down and the sensitivity of the mouse alters, so if you need to snipe someone, you put it right down, if you are in a scrap and at close range you knock it right up, its so useful, and for £45 i cant go wrong. If your in need of a new mouse and you want one which you think will make you aim better in games, i COMPLETELY INSIST that you get a BoomSlang, they are amazing!! If you wanna game on my UT2004 demo server (iGib) add me to your MSN messenger list (firstname.lastname@example.org) and i'll strat us a server. Ive Pre-Ordered my copy of UT2004, so ill be playing the proper game come next monday BUY A BOOMSLANG!!!
