You can't base your experience on one part ... I have used Halfords pro stuff for years, have only managed to break stuff by abusing fuck out of it, and anything I have broken I have had replaced under the lifetime warranty policy. Even Snap On won't warranty torx bits etc as they are so prone to breaking. And remember the Halfords pro stuff is a bargin, you can build a comprehensive tool kit for the price of a Snap On socket set.... ( Snap On IMHO is vastly over-rated, and people just pay for the name...) . And Teng make the Halfords stuff so they know what they are doing
