DITI K585 Wireless One-Handed Gaming Keyboard

I used this for my FPS games and I love it.

Quality is actually good on this keyboard, despite what I have read about Redragon in the past. The application is a little clunky but once you get it figured out it can be useful. Keys have a similar feel to my Steelseries apex keyboard.

Pun intended. :)

Absolutely 100% improved my abilities in FPS games. The space bar is in a more natural position for my thumb. The addition of the N and P keys where the space bar would normally be gives you two more keys that can be easily accessed by your thumb without twisting it or your hand in a weird way.

Battery life is more than sufficient. I play a couple hours each night and only plug the keypad in every few days. If you run it dry, you can always play with it plugged in.

This one handed keyboard works well. It saves space and the keys are very quiet. However, for keyboard/mouse gameing, it takes a little getting used to. Although the 'space; key is in a more natural position, my trained thumb keeps looking for it at the bottom. Muscle memory re-training is almost complete and I find it a lot easier. Also, a couple of keys I was used to are not there, but that's just a matter of remapping a couple of bindings.
