if you were sitting on logitech mice, then I recommend that you stay there and not try this miracle Its pros: Germany connection backlight design Ready-made macros for most games (but more on them below) quiet main buttons, have a muffled click very light, not felt at all form glide the case does not seem to bend anywhere, rather average thickness Its cons: Just a nightmare, this bottom will never take a roccat mouse again. Soft misery that lags 100 times stronger than Synapse 3, I don’t recommend setting the settings automatically . (this is another story what will happen to the computer) There are macros for games, they are not applied at all and do not work, they just stand there for a tick and that's it, I pressed the application of the settings did not work, then I turned on the key on the keyboard . as a result, the key stupidly did not work and performed a click of some mouse button ( Yes, exactly, some), neither the right nor the left button, but Windows recognizes some kind of click. The backlash of the main buttons is very tight like a stone, and then another rubbish optical mikriki push through, after the mechanics, I don’t recommend this miracle to you, I don’t know about other mice, but these optical mice are a complete bottom. the side buttons make so much noise that I have never seen or heard such a "THOUGH" before. the materials are not rough, not tenacious, I have not yet tried to drive games on it for a long time, because I immediately lost from the very first rollers. And I would also like to add about the materials . it's generally a joke, some kind of cheap plastic from the bottom . as if something was being painted. the wire is in a terrible braid, thick and the ends of the usb are made of cheap-looking plastic, as if I ordered a cord from alik for 200 (actually 1 to 1)
