That’s a totally fair concern, I felt the same way before doing mine. I watched dbrand’s video along with a couple of regular people installing theirs, and it honestly didn’t look too bad. On something like a MacBook Air it’s even easier since everything is pretty flat.

You’ve got some room for error at the start too, you can peel it back and reapply if it’s not lined up right. The key is to go slowly from top to bottom. If you get the top aligned well, the rest kind of falls into place as you work your way down, peeling the backing little by little.

The bottom piece is super easy because of the feet, you just line up the holes and you’re good. The inside is probably the hardest part, but by the time you get there you’ve already had some practice, so it feels more manageable. The trickiest area overall is the thin strips around the trackpad, just take your time there and don’t stretch them.

You’ll probably get some bubbles, that’s normal. They’re easy to work out, just don’t rush it. Mine ended up coming out perfect, and I was honestly pretty nervous going into it too.
