Given they don't have the device physically on hand, the serial number Is the only way they can verify the device and process the claim.

A POP validates the order, however the serial Is needed to validate/verify the device Itself.

You're right. I was thinking some companies might give when your lean towards 'manufacturer error' lol.

Having said all that, I must say, you've come up with a very good Idea that may well work with companies who don't bother taking the extra step when assessing claims.

Companies on a large scale such as Logitech, Lenovo and SteelSeries, will definitely require a valid serial, and that's what my previous post Is based on.

Yes there's a possibility that it could work but it is a risky method because it could indicate a counterfeit and big companies take that serious. It could trigger an investigation that could get the SE'er trapped especially if they are in the US.
So, I wouldn't advise anyone to try that method.
