A customer spilled coffee on the keyboard and trackpad of her Macbook Pro 13". I opened it, only to remember that I didn't have a Y-wing bit to take out the battery (which you are very firmly told not to remove, of course). The battery had to be removed to get to the trackpad for cleaning. Instead of just ordering a Y-wing screwdriver, I ordered this little kit because it just looked too geek chic!
While the kit performed perfectly, alas, the coffee had done its damage, and while tracking was okay, the clicker could not be restored with a mere cleaning. Perhaps a trackpad for a 13" MacBook Pro will be my next order...
I advise you to get this kit. I've messed around with all kinds of hardware store repair kits, and there's ALWAYS something missing. Not only that, the bits often strip or the screw handle fails in one way or another. This thing is built solid, and the bits are wonderful; slightly magnetized to get those tiny screws right where they need to be. Well worth the investment.
