After a quick search, I had the Logitech G13 and the Razer Nostromo envisaged. Since both for me had the same technical characteristics and I no display and not necessarily as many keys need (if you're in the Logitech G600 possession, falls already much away. ;-)), I opted for the Razer Nostromo as these, much more convenient ergonomic looked from her to me.
So ordered and as usual very quickly receive the delivery and immediately connected to the PC. From the processing of the gamepad, I must say that I have nothing to complain about, all right!
Even with the stability on my desk all is well, the game pad does not slip with me! What I find very good!
With regard to the size and convenience, this is simply a point which may be different from person to person. I'm lucky enough to have the right Händgröße apparently, because I'm without my hand to bend well everything ran. To my hand size, I'd say that's Show Average for men. And convenient to the gamepad is also, here a trouble-free operation over several hours without aching wrists or hands is possible.
For software, this can / have to be loaded from the Internet, as no CD / DVD is (or I have not found these?). But that's not a problem these days. Something stuzig I was after installation, when I had started the software and the message was that no Razer Nostromo is connected.
This was, however, connected and working well, so searching on Google and finally found the solution (in my Win7 64bit Home), and although the software has to be started as an administrator, then all is well.
The set of the gamepad is not a problem and relatively easy to do everything.
Finally, I wanted to say, it has of course a little time needed to get used to a game pad, as it is something other than a normal keyboard. I also often caught me as I am to the keyboard back. But if you stay a little on the ball or gamepad, you want it at some point not to miss! ;-)
