I needed tools to fix various electronics and such around my house and work. And the mat and driver kit fit both my, tool needs, and my organization needs.
Quite swimmingly. I've used it to repair my glasses, PS3, numerous iPhone 4's, and for my laptop as well.
I'd definitely advise anyone thinking about the driver kit to get it. The build quality on it is superb. Just above and beyond what I was expecting. Even the case and bits are extremely well made. The mat is also superb. It holds the screws in place even if you bump the mat while working on a project. Which for me, is a huge plus because I'm clumsy as all heck.
