None. Good idea, but they're just not up to par. Not just these, but all autolock pliers. I even tried it with strong hands. These are slightly smaller. It's easy enough to adjust to the desired tension, but my problem is handling the auto-locking pliers. If you're into automatic vices like pliers, then you want to be able to operate them with one hand, right? That is the goal. You position the part and grab the pre-installed locking pliers, and it's almost impossible to wrap your hand around them once they're open. I have medium hands. Put on a medium-sized glove. Broad palm with medium length fingers. You must have fairly large hands with very long fingers to easily pick up and use it with one hand. The engineer on it must have been a big man. Otherwise well made, good fit and finish, just won't pass the usability test. Just note that you're better off buying these for one-handed use and have an average hand size.
