This tool is extremely helpful while you wait for Apple to fix your laptop under warranty (and they should fix it under warranty). I'm glad to see Apple is moving away from the flawed design in newer products. I really liked the keyboard on my 2013 MBP. Can't stand the new keyboard design and absolutely despise the touch bar.
