@172 DRIVER I don't see how you arrive at that conclusion!
Like it or not, every commercial enterprise is about making money.
If you make a faulty product, wether it be a £5 electric kettle or a£600 phone or a£30,000 car, you issue a recall and replace the "unfit"part with a merchantable one, at your own expense I find it staggering that aviation folks are so willing to accept top-dollar fully-certified stuff that later turns out to be worse than a cheap Chinese knock-off.....then, they bend over and get reamed again ,for another "certified" item
Do you not see, that all this "rigorous safety control" is bought totally into disrepute?
Pay £3K for a watch, then find it's a "Bolex" you'd be upset.....OTOH, pay $15 for it, you'd be happy If you paid £3k for a genuine "ROLEX" You would expect a superbly engineered precisionChronometer that lived up to all the manufacturer's hype.
Being stung for a product that is NOT WHAT IT CLAIMS TO BE is downright dishonest. An honourable company would refund commensurate with unused "life" and an allowance for the work, disruption and time out of service that THEIR foul-up had cost the customer......as it stands, this debacle has to translate to higher ticket prices for the punter who actually uses the airline.
It really isn't a simple matter of "suck it up, tough luck, you bought a substandard product"
