I was never impressed with them. Too loose fitting, kinda like using a metric on a non metric nut.Theres a reason they are so cheap.
I got one just to prove it was junk to my younger co workers, broke it on the first try.
Did you send them off to get a lefthanded monkey wrench and half a dozen skyhooks too?
Love to see how one would hold up to my 1/2inch snapon impact.
