The ergonomics of the gamepad is very well studied and fingers fall naturally on the keys, I'm a man with normal-sized hands, and I can access all the buttons (provided you play joystick) ...
As for the joystick, it is where it sins, he is much too small, I suggest you replace it with a joystick Joystick Xbox 360, the movements are made naturally and it saves us 3 keys on the keyboard for change, combined with the right mouse click, straff is quite effective.
Fully configurable, with a large palette of color, it is very nice, the screen is a little more significant, I use it mainly for WoW, but I do not rule out in the future that playing with others games, especially as in some games like VSWG the keyboard / joystick change, no longer have reason to be with this fabulous Joystick, with a combo controller / keyboard.
So I removed half a star for a little small joystick and another half star because I took an offer reconditioned "like new" and that I had a slightly scratched screen.
I hesitated with the Razer Tartarus in the same price range, but I preferred the G13 compared to the key sound (the razer is very noisy), and especially that he has over the keys to Tartarus same price, otherwise you have to see the range above and take the orbweaver (for 60 euros more ...).
I combined it with a gamepad Logitech G600 and I find myself with the opportunity to have hundreds of binds easily accessible.
Then logitech has nothing to prove the level of product robustness unlike Razer ...
The grip is very instinctive I find, personally, I was playing with the keypad and arrow keys before that, although I was quite competitive, I was less comfortable than regular keyboard, the G13 came solve this problem. :)
