Review on Get swift with Logitech's M185 Wireless Mouse in Grey! by Agata Andrukiewicz ᠌

I have been using the M185 model for a total of 8 years. In 2022, I bought the same mouse as a gift, but of a new generation - with an abbreviated Logi logo instead of Logitech. Six months later, this mouse began to fail the wheel - the pages jump up and down when scrolling. Exchanged under warranty for the same. The new mouse worked for half a year and the problem with the wheel started again. I handed it back, took the money and bought a mouse from another manufacturer. But still, I wonder why the mouse of the previous generation still works properly, but the new generation does not. I suppose that in the new generation the design was reduced in price and a mechanical one was installed instead of an optical wheel position sensor. If we compare the markings of old and new mice, it can be seen that the designation of a certain optical sensor has disappeared in the new mouse (highlighted in the photo). Maybe it was the wheel position sensor. Correct me if I'm wrong
