It could very well be the perfect mouse for MMO games. But the manufacturer decided to save on cheap components. Has some pros: 1) Add. a block of 12 buttons is an extremely useful thing in an MMO, or, for example, in Spellforce 3 (4 characters with 3 abilities each - just 12 buttons). 2) The G-Shift button almost doubles the number of buttons, although it will take a very long time to get used to it. 3) Availability of profiles Has cons: 1) The microswitches in the main buttons are just disgusting quality. About a year later, a double click appeared, first in the left, then in the right button. Every 3-4 months I have to stably disassemble the mouse and straighten the contact plates in the mics (I don’t want to solder). I even made holes in the Teflon pads so as not to peel them off every time. 2) After 5 years, the wheel stopped responding to pressing. Now pressing the wheel binds to pressing G-Shift, which is why the problem of double click came to this button too :D
