I ordered an S6 on 02/10, it’s out for delivery today, so eight days from China to the UK.
Edit - and it’s just been delivered to a random location. Need to follow up with Evri now to find out where the hell it is.
Thank you for sharing this data! It’s amazing that you keep such close track of the packages, and the shipping is indeed extraordinarily fast in the vast majority of cases–all 73 of these orders arrived faster than mine 
I must have been very unlucky with the last-mile carriers.
