Please remember that any mention of competitors, hinting at competitors or offering to provide details of competitors will result in an account suspension.

Manufacturers or resellers only pay for return postage for faulty items if you are still within the standard 14 days CCR (Consumer Contracts Regulations). Once you are outside of that then it is the buyer that needs to pay for this. You probably should realign your expectations with what is reasonable.
You could expect the Russians to admit to using nerve gas to try and kill 2 people on British soil and killing another Russian business man in London but then it would not be a reasonable expectation.
I've been in I.T for over 30 years and I can not remember a company paying to send faulty stuff back to them (outside of the 14 days); Logitech used to send out replacements even before they'd received the faulty item back but I doubt they still do that.
