I love my Grey Pneumatic socket sets. I DIY all my own repairs, and most of my family's. These socket sets are excellent for tossing in the trunk with my my Milwaukee impacts, and a couple other hand tools. I only wish the blow moulded cases were more similarly sized. I wouldn't hesitate to recommend these sets to any experienced mechanics, as they are an excellent set of tools for the money. My only warning would be, given the nature of Molybdenum, don't use these in junction with a giant breaker/cheater bar, save that duty for traditional chrome sockets. Molybdenum is excellent for absorption of impact, not so great for the EXCESSIVE torque that can be applied with 2 feet of breaker bars. These especially being thinner walled than traditional impact sockets, would probably stretch or break easily if used in that manner.
