Looks like clones are stepping up a notch, if true this one is made from 316SS which is 99% as close to the original (original uses 316L SS i believe)
316L is lower carbon and thus softer, so if this clone has the measurements right, it could be better than the original (harder wearing) at a fraction of the cost.
It's still have the cheap and nasty soft o-rings so might be worth spending £9 and getting a genuine spares kit
