I had a DEXP mouse (a copy of this mouse for 300). She had dangling side buttons, an initially non-working sensitivity switch button, and about six months later the wheel died. But she also had pluses: a very comfortable shape and a perfectly working sensor on the rug. Therefore, when choosing a replacement, I was looking for a mouse of just such a shape. When I saw this mouse, there was no doubt that it was necessary to take it. It was one to one with my old mouse, but from a "good" manufacturer and at a decent price of 800. But it turned out that DEXP is not a fake of this mouse, but it is the same mouse, only with different stickers. All the same shoals came out as DEXP, but even earlier. I do not recommend taking, the quality is terrible.
