It's not 'our problem' after 6 months.

If I have a problem with a product that's within warranty, then I don't want to deal directly with the manufacturer. I want to deal with the place I bought it from. It's a severe inconvenience that if the device is faulty after 6 months, but within a the guarantee period of the device, then it's no longer 'your problem'. I won't ever buy any large value items from you ever again. I'll stick to the places I know and trust.
