I spent a considerable amount of time picking the best set of heads and bits from a large number of options, and this is the one that you require: I purchased a set of open-end wrenches and a set of auxiliary tools (a tape measure, pliers, hammer, and scissors) separately. At this point, you should at least start your own transportation service. There have been other occasions in which the set itself has been of assistance under trying circumstances. It's too soon to talk about the strength or reliability of anything, but I don't think there will be any issues.
