I'm using a Logitech G300 mouse, and a Razer Lycosa keyboard. The keyboard I got to match the blue case lighting of my PC, and I just recently got the G300. Both are amazing IMO. I needed a new mouse, and the Logitech G300 looked quite nice, and sounded nice from the reviews on Newegg. Ordered it yesterday and got it today, and its amazing. Especially considering I only paid $29 for it!
I used to wonder why people paid more for "gaming" mice and keyboards, but now I know. Macro buttons are useful (and often fun to play around with
). Although occasionally I get booted from FPS servers for some macros (rapid fire piston ticked some people off...).
