Depending on your product (more like manufacturer) I couldn't agree more. Plenty of failures are small, localised and with some learning easily fixable!
Replacing the frayed cable on a good pair of headphones, usb cable on a functning mouse or even broken display as part of a laptop.
I recently decided to take the more challenge task of repairing a swelling battery in a phone. I didn't have to worry about the back glass as it was already swollen such that the glass had cracked. It was surprisingly easy to take apart, remove the screws and little legos[0] get to the battery. Closing it up was extremely rewarding, as if I'd completed some hard surgery and was stitching just up the patient.
