Former owner of various Razers (don't live mostly for more than a year) Logitech G600 - mouse masterpiece! It served for a long time and the buttons were just right for me, but it broke for 4 years. Logitech G102 is a good mouse, but few buttons and lasted a little over two years. Bought now this "miracle in feathers" Buttons: if you press the side buttons, then the figs will break your hand, fingers to reach the middle ones, if the hand is closer to the middle ones, then the figs will reach the side ones, which are near the left click. I can not imagine a person who could manage all the buttons adequately. Fortunately found, the wheel is fixed) I wanted an easy replacement for the G600, I got G . on a stick. It would break faster, I'll buy G102 again and I won't suffer any more garbage.
