not bad....my only concern is,did you have to heat the wrench/metal up to bend and form it into shape?.....I'm not 100% sure,but that may have weakened the metal substantially....good luck,and use alot of care on those first initial kicks.
I know if it were me,I'd dish out the money for a new one,and keep the home-made one for emergency use only.....just my thoughts.
