Perhaps I was very "lucky" to have time to buy this mouse at the moment when it cost 4200 (in Europe it costs the same in euro equivalent, so consider buying without extra charges), but even so the price for the mouse is very high, however , I canโt call it unjustified, regarding the same blades that I have been using for years since 2022 (I changed 3 pieces during this time), the difference is immediately noticeable. It is much more pleasant to hold in your hands and the sensor does not fly off. You really need to get used to the side buttons, firstly, the silver button is, in principle, quite far away, which makes it convenient to press it only with a claw grip, and secondly, the button that is located directly above the back and forth buttons is a lever button , that is, it is pressed both up and back and they are considered different, that is, both of them can be bound to different keys, just an interesting solution. The backlight is diverse and is configured in all mental and unimaginable ways, up to the fact that the backlight can change depending on your amount of HP in games. And it works in sync with other peripherals, I canโt check this, because I havenโt planned to buy their other products yet, just as a pleasant fact, especially since they have left our market so far.
