Instead of indulging our throwaway society, but I have cut the cable and re-soldered. That in itself was not a big problem. Aaaaaber:
1 strain relief and bend protection? Sorry, but for an electronics company Philips as it should after decades be possible to construct a strain relief which, lasts longer than two years. Especially with a product whose product name would suggest continuous professional use: "Salon" Dry. Let's see how many years an additional milk tube at the problem location helps the hair dryer.
2. Proprietary screws? Philips, nor are you? A hair dryer is now not Rocket Science and in principle quite simple built so that you have a cable break but still can just fix with expertise and care? Triwing? Y-Type? Nope, Philips has since verbastelt extremely rare triangular-cog. A profile that you can still knows of openers for train doors, unlocking of hydrants and drive-through locks. I never imagined then only times cope honed a suitable Allen key.
... And yes, I think about what I'm doing (electronics - power engineering) and from my experience I know that the dangers rather be because a hair dryer or wet hair tangled when someone starts with the screwdriver herumzupopeln in hairdryer. Just at this point, someone is not aware of the circumstances that possibly because the wire is exposed and could easily turn take, I would have a little more prudence expected.
Summary: One point. ... Pity for the otherwise successful product.
