1. Microsoft Band, a month after its warranty expired (bought in the USA), they still replaced it for free because of plastics wear, a common issue for that version
2. GF's Surface RT: faulty touch screen 1 year and half after she bought it, replaced for free, no questions asked, they even sent the replacement before I shipped the faulty one
3. GF's Lumia 925: she thought the pictures taken by the back camera were yellow-ish, she got it replaced with another brand new 925 for free. Six months later we bricked it trying to install a Windows 10 Insider Preview, replaced for free with a Lumia 830
4. My Lumia 1520, sent it in for repair because the battery was wearing out (it lasted a little more than a day instead of 1 and half/two), got a Lumia 950 XL instead
A friend of mine also got his Surface Pro 3 replaced for free.
I went ahead and did it but I struggled since it was not a small purchase price. I received the replacement and sent the defective unit back. Expecting the hold to be released with in 2-3 business days after they received the defect unit. Nope. They ended up holding the money for 15 business days.
I don't know if I'll ever buy something Microsoft again.
I'm not going to pretend that Apple's customer service is horrible, but I can safely say that they aren't special anymore. Maybe I've just been incredibly unlucky, but simply put, their customer service is lackluster at best.
Edit: Just to be clear, this is all consumer level support.
