1. Failed Imac hard drive replacement.
2. MacBook failed LCD replacement.
Both went well! The Pro Tech tools greatly facilitated the Mac work rather than using a collection of tools acquired over time geared largely for PC repair.
I did have to use a needle nose plier to grip the phillips head drive to loosen a "frozen" screw. Maybe a small crescent or box wrench to grip the hex shaft of the drives would add an enhanced feature to the set. Otherwise...top notch!
