So I just bought a Moshi keyboard cover for my new 2019 MacBook pro however I just read apple warning that it's not advised due to lack of space and indeed I can see that it's interacting with the screen when closed. Question: Do you use keyboard cover or not? Those who don't are you able to clean your keys efficiently? How does it look after a few years of use? like new or bad? Moshi states that it use a special material which is not causing any issues with the new retina screens even if they get in touch with each other but I'm looking for some real feedbacks here!
