Needed to get the memory out of a MacBook Air (my son just let a bit of sugared coffee go into the keyboard and it finished by destroying the motherboard hence the need to open the case, because it would not event start in target mode).
This is the first time I have been able to open one of those "Books" without damaging it. Precedently it always ended with one (or more) screw slightly damaged and hard to reuse anymore, or a scratch of the case because the screwdriver ripped out.
Nothing of that with this "54 Bit Driver Kit". 5 minutes and all the case's screws where unscrewed, no rip, no scratch, every tiny little screw still usable. The right tool at the right time ..
A must have when you want to go inside any device "Apple made".
Shipping to Europe by boat can be quite quick : 1 week only in my case.
