Broken mouse worth almost 2000r. It broke after the fall, so there could not be a guarantee. So I decided to give it to the service. There it lay for 2 weeks, after which I was called back and told that the repair would cost 1200p. Of course I did not agree. I came home and decided to disassemble it, it was always interesting to see what the mouse was inside. I broke and broke. The optics (the source of a red light) jumped out of the patch and shone to the side. Optics, her mother has jumped out of the back!!! And for putting it back, I wanted to cut off 1200!!!! I pushed back and it worked out! Now I seem to know why a broken thing is forbidden to dismantle.
