    I'm surprised how well it actually works, i bought it to do car wheel alignments. Most outer tie rods are 16-13mm so this was perfect, found that it will even work on 17mm! Makes toe adjustments a breeze, now if only they'd hurry up and come out with the joker XL for the tie rod jamb nuts (19-24)
