The protector itself is amazing on my 13 inch macbook. However, you have to apply it PERFECTLY for it to be used properly. The size of the protector is the exact same size as your actually screen and only leave about a nanometre of room for error. The application process was difficult, so if you plan on purchasing it, you need to be able to apply it well. The protector actually makes my screen look better oddly enough, on top of keeping scratches and dust off it. Shipping took almost 30 days though !
