Review on Whizzotech Repair Replacement Screws & Screwdriver for Unibody MacBook Pro Retina 15'' A1398 + 13‘’ A1502 A1425 Bottom Case Set (10 Sets) by Kevin Vanlaere

Perfect for 2011 Mac Air 11" laptop. I was missing 4 screws and was able to replace them in less than a few minutes with no problems. Note: There are 2 long screws in this package I don't know why or what for but I couldn't use the longer of the 2 sizes, only the smaller one. There were only 4 smaller sizes in my package. The bottom of my laptop was open causing my trackpad to malfunction. Now it's completely closed and everything works fine.
