I had to buy a new mouse after replacing the computer and monitor with 4k. The old one refused to work normally with the new system. The choice fell on the G603. While it works great. And I don't regret buying it. But I had to adapt to the shape: I'm used to more elegant mice, and this one is somehow very plump along the vertical axis / in the "priests" area. And also at the expense of plastic - I don’t know that some reviewers praise it so much. For me, the rubberized version is much more pleasant. And this is purely economic.
