This is an MMO mouse.
The 12 buttons on the side to be coated with MMO capabilities of the Power Bar!
In an MMO but you have to use much more than just the Powerbar.
This reduces the device to a 5 button mouse.
LMB and RMB Wheel button are default already occupied then remain 2 all keys left you can assign any.
My Logitech G510 has 10 soft keys, which are already full, and do so without Powerbar!
With 2 buttons I come with the best will not, or I let half Powerbar away and so the mouse has missed its use.
That said, I personally found the mouse much too small, I do not have big hands but the thing here is yes winzigst, ie 20% more likely they already have.
Processing leaves much to be desired, unclean composite edges and the materials used are very receptive to fat fingers.
After 2 days I liked the mouse no longer touch because it just yet babscht, the feeling is in my old Logitech mice (MX500 - MX518) always occurred only so after 6 -12 months.
Positives:
The LEDs of the Naga looked extremely cool, because there are ma nothing to complain about.
What I that you can save the key assignments online in a cloud and nice Syncronisieren also found was
because Logitech ne page from my G510 could with tens of profiles, etc. I can to any Windows program Neuinstall front. (Yes I know that you can export and import previously later, but who thinks because there before it?)
