Really needed for any Macbook
Apple's butterfly keyboards have really taken a lot of criticism, most of which is valid, for too little key travel and too much susceptibility to contamination. This cover will help a lot with the latter, preventing dust or crumbs from falling under the keys. This particular cover is a perfect fit, strong but without adding too much tension to the key strokes. Very durable so far. Probably the best keyboard cover I have ever bought.
