Greetings from Hostivice
I am afraid that the Alza warranty is NOT the official Applecare.....as someone in the thread mentioned spilled drinks....that would certainly not be covered by Applecare. My guess is that this is an Alza coverage, similar to Datart, Mironet etc.
I would advise to get the original Applecare. I have it on my 2011 15 Pro. About 6 months ago, I got an error on the battery - message was that I need to replace it. Strange, as I did not notice any issues.
Sure, Apple covered it. I did get a new battery. But compared to an Apple Store in the US, this was a hassle, as service is handled by the few third-party outfits. One outfit wanted some 700 Kc to do this within 24 hours. In the end, I did this at the service center at the Casablanca building. They had to first get the replacement authorised by someone in The Netherlands. Then they wanted to keep the Macbook, so the bad battery could be shipped out, before new battery arrived. I was able to keep the Macbook without the battery, running on AC, for some 4-5 days, before the new battery arrived.
Even with this "bad" service, i do think I will get Applecare when I get an MBPr later this year.
For comparison - my daughter had bright spot in the middle of the screen. She made an appointment in an Apple store in Denver. The "Genius" looked at it, stated, that she probably bumped the screen, but as she was an Applecare customer, they would replace it free of charge. Sent us home, called in 3 days, when the replacement screen was delivered, exchanged it the same day.
