After a long 4 years using the Logitech Dinovo Bluetooh mouse and keyboard set, i've noticed this set aint that good for gaming. Also the thing keeps loosing sycn once in awhile. So i've been looking, and i have found a mice and a keyboard of my liking, but i have two of each, and need some knowledgeable people to help me decide on which would be good. Keyboard: Logitech G15 Version2, or Razer Lycosa keyboard Mouse: Razer lectheis, or Razer Copper head Those are it lol. Thanks in advance.
