Review on Logitech M100 Corded Mouse in White - Efficient and Reliable (Model: 910-005004) by Stanisaw Muter ᠌

[1] - The button is easy to repair. 2 ways: with soldering and without. With soldering: we replace the microswitch with a similar, new one. Without soldering: We disassemble our mouse and carefully (with a needle) open it (open the latches on 2 SIDES so that the cover is removed VERTICALLY, otherwise there is a risk of bending the filling) microswitch (a small brick with a tiny button), take out the plate and (there are 2 options) insert a new one from a similar microswitch, or bend the one that is. If your option is the second: very carefully (you can’t bend strongly - it will break) bend the protruding tongue so that it becomes almost straight and at an angle of 35-40 degrees, then gently (with tweezers and helping with a needle) insert it into place (first insert the base into a very small groove , then we click into our groove and the tongue itself) and close the cover of the microswitch (not forgetting the tiny button). * [2] - Polish the plastic with a soft cloth moistened with nail polish remover (or diluted acetone. Pure acetone will melt the plastic and the mouse will "leak" like on fire) Wipe the wire with a cotton swab slightly moistened with acetone (after no more than 10 seconds, wipe it with a damp sponge / cotton wool to wash off the remaining acetone and dirt (otherwise the acetone will corrode the wire)) Nail polish remover is not so effective here, but still effective.
