I have had several Gearwrench sets and I am glad they have a lifetime warranty. Several of the wrenches have faults in them. I had the 10 mm and my 5/16ths wrenches have defects and automatically change the lever while I'm twisting on it.
I will also tell you these were not individual wrenches, they were sets and no one wants to break a set to give you a new wrench for a broken one. You have to use this form.
