I love my logitech mouse, but I dont think I'd be interested in this keyboard. most backlit keyboards (logitech, saitek, etc) dont have that bright of keys, and you end up only able to really see them in complete darkness.
If you want a good backlit keyboard get a Deck. They have bright, quality LEDs under every single keycap, cherry switches, diamondplate back cover, customizable keycaps, good warranty even if you mod the keyboard.
