4 years and the battery needed to be replace. It seems most Apple product repair guy comes to your home to fix the product instead of you going to their center.
After disassembling the Macbook Pro, we found that the previous fixer did not fix the liquid issue at all, instead it was leave dry there, they don’t even bother to wipe the mark off. Well, missing screw as well.
Sometimes when you get premium stuff, you really need to get premium support as well. There is nothing one-time, even for premium product.
