The usb reciever for my logitech mouse broke a few weeks back(Was my own fault, it got bent). So I decided to see if I could order a replacement reciever, I called logitech and they said that they didn't have it(Of course they didn't the mouse was 2 years old). BUT then they said that the would send me a NEW mouse! Even though it isn't covered by warranty! So yesterday I recieved it, it's a Logitech Lx8. It's a full size mouse(My old one was a small laptop one), it's comfortable and I really like it. That's what I call good customer service!
