Unfortunately Apple quality has been piss poor in the last few years. There were issues when Steve Jobs was in charge but since he's gone they have really multiplied.
No matter what people say, nobody will care about your company as much as yourself. Steve co founded Apple from the ground up, which was why he was so obsessive over everything they did.
These days its a mixed bag whether you get a good product or not from Apple. I exchange every Apple product i buy between 5-10 times before I get one I am happy with.
Luckily for now Appls has excellent customer service when something does go wrong. Even so it is slowly shifting with little changes being made which are less focused on customer satisfaction. Last year when I had issues with my iPhone 6 Plus I was able to keep hold of the iPhone while they sent a replacement and i was allowed to have both in hand for comparison purposes. Now they have scrapped this option completely and they won't even send you a replacement until they have received the old handset.
