Mine is still going strong. Second Apple product I ever bought (first was an iPod many, many years back), and since I've been a bit of a convert! The battery only lasts about 2-3 hours now, so I replaced it with a new model last year. It did have issues with one of the keys but it seems to have come right. I much prefer the 4 USB-C ports over the array of various different ports on the 2012 rMBP, especially because I can plug the charger into either side, but I do miss magsafe a little.
