I bought a Logitech M525 wireless mouse and the scroll wheel is not working properly anymore. Scrolling up works sometimes but scrolling down is usually left without any response. Since I couldn’t find any visible screws could you help me how to disassemble this mouse? Thanks

I just fixed it. You got two screws at the back of the mouse, you have to take out those covers - just google how to disassemble any logitech mouse. You remove those two screws, then you have to SLIDE the mouse (two parts), so you remove the top part. Then disconnect small sable, clean everything, remove dust and hair and all the stuff, and then just put it back. I even removed wheel and wash it… good luck, mine is working now as new
