(very much the same like the Sharkoon Skiller and the Sharkoon Drakonia)

Logitech G500 mouse and Logitech G15 Gen1 keyboard.

Would like a new keyboard, was looking at some mechanical ones but would prefer to try them before I buy but almost no place around me has any out of the boxes to try.

Mouse: Logitech M510

Keyboard: Logitech Cordless Desktop Wave (yeah, the mouse that came with this set is dead, so I got a similiar one)

Microsoft ComfortCurve 2000 keyboard
Microsoft TrackBall Optical mouse

Yeah, neither are recommended for gaming, but.. eh.

Logitech classic keyboard - Wireless, not exactly sure which model it is though. And a Logitech Anywhere MX mouse.

Perixx MX-1000 Iron Gaming Mouse and Gateway KB-0532 Elite PS2 Keyboard

Any keyboard with the sleep button anywhere accessible (like right near the damn arrow keys) is far from amazing.

I see many people have razer products and I'm thinking in buying a razer blackwidow. Are razer products that good for gamers?
