MACK vs Goldtec Hubs

this little pile of Polish precision engineering arrived on my door step today. Ironically my girlfriend is in Poland at the moment but they were easier to order from Buckinghamshire. Only took 48 hours.
They look and feel nice, but time will tell..

Ok I don't know Macks. Never heard of them before this thread. But the above looks identical to another Polish production that was designed by a courier, for couriers, and tested on couriers. Manufactured by a helicopter engineer and in a class of its own for weight, finish, smoothness and the chunky lockring:
