I decided to please myself on the DR by buying a new mouse (although the old one is still on the go). Yep, pleased. The box from the mouse was not sealed, but did not attach any importance to this. A chip was also found at the input of the loading port and again did not attach any importance. I used it for less than a week and today during work the mouse scroll wheel just stopped working. Scrolling does not work in any program. The middle one itself, moreover, works, but that doesn’t make it any easier. As I understand it, I came across a "restored / soldered mouse". Very disappointing. I'm making a return! I'm sorry, but for that kind of money . you still want to have a new mouse, not a refurbished one. Probably now I will take it from another seller, albeit more expensive. In general, I have no complaints about the seller. If there was a replacement function, not a return, then I would certainly use it.
