I've got my MBP on November 2016. Keyboard was ok until one day key "R" didn't click on pressing (it still registered). I've tried blowing air from different angles, shaking, fiddling under it with thin piece of paper to no avail. One day I've pressed it, and it did click, and then it popped out. By then Apple had free servicing action in effect, so I've went to local store and they replaced my top body with new one (also replacing battery, touchpad and speakers). Touchbar is completely useless for me. If anything, it freaks me out because there's absolutely zero feedback to finger when I accidentally touch it.
