I'm here to tell you all about the worse mouse and service I've ever experienced! It's called Razer Boomslang 2000 and Kärna Precision! I bought my mouse 2 months ago for about £80, the best way to waste money is to do the same! It took the mouse about 1½ moth to break down. The left mouse button started lagging and soon it completely frooze! on top of that it doesn't feel very precise, infact, I now use my http://www.sandberg.it/sandberg/hardware/63071.jpg 2 button, no scroll mouse wich gives me the same result (the no1 spot - bf42 ALWAYS). Well, that wouldn't bother me if it hasn't been that the company won't return my emails... And I've send 15 since i got the mouse (over 2 months) The lack of service is fustrating and the worse part is that the company haven't even released a WinXP driver??? The last driver was created nov.2000! How lousy is that?? The company can't even provide the customers with a propper driver for a common used operating system! DON'T BUY THE RAZER BOOMSLANG MOUSE - IT'S NOT WORTH IT!
