The main disadvantage is that the scroll wheel broke, it just started spinning and crunching tighter and after a few minutes it got "free rotation", while the scrolling stopped working. I didn’t drop the mouse, I didn’t bang, I don’t know what exactly broke, because I handed it over under warranty. They can’t replace the mouse in the store, it’s not available, but they can return the money, but a new such mouse in other stores costs at least 5000, and I bought for 4200, as a result, as if under a guarantee, but in fact pay extra 20%. Now I do not know what to do, which mouse to buy. Everything seems to be in accordance with the law, but the situation was not resolved very pleasantly for me, and I cannot be called a satisfied client. In general, the mouse is suitable, it worked clearly, I considered it to be actually an ideal mouse, but alas.
