A really good method of checking the quality of a manufacturers tools is to have a look at their 1/4" drive socket set.
The good ones have sockets up to 9/16" or 14mm.
The bad ones go to 7/16 or 11mm.
Unfortunately the good ones are expensive but they will last a lifetime unless you lose them or someone borrows the permanently.
Check out Stahlwille, Snap-On, Proto, Britool, Hazet etc.
