Service life - more than 2 years. The flight is normal, no complaints except for the worn out silver coating. The mouse is ideal for most people. My advice to you. I will reveal my life hack about how to choose a perfectly comfortable mouse for yourself. To do this, we go to the nearest hypermarket where you can take the goods in hand. We need it because. all mice are now packed in a blister that exactly repeats the shape and corresponds to the size of the mouse (a couple of millimeters do not count). So, let's find that one. which seems to be pleasant, we remove it from the window, and simply take up the blister like a mouse, as if you picked up your mouse, and evaluate how the mouse fell into your hand. So you can pick up the ONE that will sit in your hand like a glove, and become an extension of your hand. Good luck to you.
