It's funny, but this is my second G603 mouse, and so far I haven't handed over the first one to the service and compared point-blank - they turned out to be very different in terms of how tactilely and with what noise the wheel spins and the buttons are pressed. Some pros: Despite everything, alas, one of the best mouse options for work and quick switching with two devices (computer + laptop, for example). The G logo on the mouse is erased in a few months, but for me it is rather a plus, the mouse does not catch the eye and the shiny logo does not draw attention to itself anymore. 2 years warranty. Has some cons: Just a year and a half later, a double click appeared. Logitech does not have its own service in the 2022 (it's just "hello"), and the support is enchantingly tight and long, on a buggy site. You will have to contact the store if anything (you will be sent there in support anyway). What to do if the store stops working by this time is unknown.
