Had roughly the same experience with Logitech when my MX518 died. They asked me to email a phone camera pic of the label with the serial number and shipped out a brand new G500 right away. No hassle over troubleshooting, no wasted postage mailing back a broken mouse and waiting two weeks.

It's nice to be treated like a customer rather than a fraudster, and I definitely factor in warranty claim friendliness when I buy new hardware nowadays.
