The installation is very simple, similar to a protective film for mobile phones, with a little skill and a credit card you can get it easily without bubbles out. The fit is also satisfactory, unfortunately, the hand did not fit 100%, but this is hardly noticeable when the laptop is opened, and the apple lights. The only downside is the color of the sticker. Unfortunately, these come out not as bright as they are shown in the photo. The colors are rather dull. Still, making a nice idea his Macbook from the others.
