Somehow, due to the combination of small minuses, the best mouse in the world (and simply for its price) does not pull. Next time I will try something different. Another braided wire works well as a dust collector. This is not taken into account as a minus, just a note. P. S. while typing hung and cut off. Probably offended. Pros below: - nimble, excellent parameters - handy - beautiful - a set of weights. With its cons: - the wheel in the "step by step" mode is somehow rough, spinning with a loud crack. In the "free" mode, it is too dangling, without inertial. In the end, neither is uncomfortable. - works unstable at times. Either it works to turn on the computer by pressing a button, or it doesn’t. Either wakes up from sleep mode or does not wake up. Sometimes freezes on the move. I even thought the wire was bent. - The software is somehow indistinct, the interface is not very good.
