I have a 15inch ~mid 2014 model that works very well still! The only problems I've had were the battery losing juice, and the screen went out suddenly. The original screen also had peeled a bunch which turned out to be a manufacturers defect from the 2014 models. I took it in to apple and ended up spending ~$500 to repair the battery and the screen, and I'm almost certain that they gave me back a brand new 2015 model a few days later. It's like a brand new laptop. I really like this model and plan to keep using it as long as I can.
