I bought this screwdriver in addition to working on my MacBook Pro. It was important to have a suitable for small screws the bottom tool. This screwdriver fits and does not damage the fine screws. Perhaps the material is a little too soft for everyday use, but even if one unscrews his device in, it's just right. How often do you also exchanged its hard drive or memory? Eben, usually once in the whole operation life of the notebook.
