I don’t think they look that bad Dom, they are only £15 so worth it.
I’ve had one fake one from a bike I bought. As soon as I got it off I could tell and I didn’t even realise they made fake headsets. I binned it as it was rough too , which I’ve never seen on a king.
For £20 you can get a nice FSA which will far nicer quality and legit.
I bought a bike about 6 months ago just for the king headset as it was turquoise. Bloke looked at me gone out when I asked if i could just whip stem off to check bearing race.
