I got a good deal on a couple of UltraFine 5K displays a while ago - so good that it made it worth upgrading to a 15" MacBook Pro that could drive them!
I ordered a relatively high-end model - 2.9GHz/512GB/460.
First one arrived and the top case was mis-coloured. Here's a picture of it next to another space grey MacBook. It looks like one is silver, right? Well, they are both meant to be space grey! A few keys had a terrible high-pitched click, too.
Apple agrees to send me another.


Second one arrives and the Touch Bar is tinged pink. Not a software issue. Looks terrible. Apple agrees to send me another one they've received one back. (Pictures show good one vs. tinged one.)


Third one arrives and it won't wake from sleep. Blank screen, unresponsive. SMC, NVRAM, OS reinstall, safe mode, etc. etc. - no fix.
It occasionally also won't go to sleep, leading to me finding a melted chocolate bar in my bag one evening next to red-hot, suffocating MacBook.
It's been three weeks now, so I take this one to the Apple Store.
They have a higher-specced model in-stock. I pay the £300-ish difference to avoid waiting another week or two for a replacement to arrive from China.
Forth one - I get home, and it won't charge. "Battery is Not Charging". Sigh. Again, resets and reinstalls do not fix. It isn't the charger. It's also scratched. I drive back to the Apple Store.
Fifth one - all looks good! Until I plug in my screens. Kernel Panic. And again. And again. (They worked fine with the other four.)

So many hours and trips wasted. I guess it just wasn't meant to be... I will return it and wait Mac-less for WWDC I guess!
In fairness, Apple's customer service has been good throughout. But this quality control is just ridiculous.
Let me hear your horror stories... or am I the only one!?
