Well my launch day 6 Plus Gold had a tiny cosmetic defect. On the edge of the glass by the headphone jack area, there appeared to be some extra white paint or a debris that got stuck in the glass.
I had to wait till the Apple store got some 6 plus in stock (Since it's within 14 days, I used the return/exchange route and not the genius route). The 2nd one had a pinkish tint on the bottom and was quite noticeable. Next day they still had the 6 Plus Gold in stock so I went and returned the other one and exchanged for another 6 Plus Gold.
This one is perfect
.
I'm thinking of going back and exchanging it for the Verizon model when stock becomes available. Although, my AT&T 6 plus is unlocked since I purchased Device Only. But not sure if it's worth it. Especially when I travel to South Korea, I would like to use it on their network.
