One more thing about the dynamites wrenches are the strong hex wrench itself. My friend has a integy set, and he just bought them and had snaped the 1.5mm hex head off the driver. It might have been a flaw but I have had my wrenches for about 3 years now and none of them have yet to show ware or signs of brokenness. Though one of my wrenches(small 1.5mm wrench) has a bent shaft but that is becuase i using it incorrectly
