Review on Mouse Logitech M100, dark gray by Mateusz Wodarczyk ᠌

[1] - Fixing the button is a breeze. Soldering and non-soldering are the two options. The microswitch is removed and a new one is soldered in its place. Without using solder, we disassemble our mouse and carefully (with a needle) open the microswitch (a small brick with a tiny button), remove the plate and (there are 2 options, depending on the microswitch) either insert a new one from a similar microswitch or bend the one that is there. If the second option appeals to you, gently (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, insert it into place (first insert the base into a very small groove; then, we click into our groove and the tongue itself); finally, close the cover of the microswitch (don't forget the tiny button). * Polish the plastic with a soft cloth dampened with nail polish remover (or diluted acetone). The plastic mouse will "leak" and catch fire if you pour pure acetone on it. Use a cotton swab dampened with acetone to wipe the wire (wait no more than 10 seconds, as the acetone will corrode the wire if left on for too long), and then wash away any remaining acetone and dirt with a damp sponge or cotton wool. In this region, nail polish remover is less effective than elsewhere.
