YES #$#$K!
My #($& Logitec mouse did not accept my new batteries: It’s #$( not working
So if your cordless mouse does not work: nothing works :-(
the 16 Ports switch I brought today: #$(# broken after 30 minutes :-(

It’s HOT, THUNDER, BLITZ and a no working mouse: I’m sweating. This is not what I call good life.

Lucky me: I’ve a spare PS/2 Mouse. That’s back to living.
