Specifically bought them for the tweezers.
Over the past few years tweezers have been terrible for some reason.  I deal with the crazy grandpa ear hairs and have gone through about a dozen.  A lot of the mass produced ones were slightly off.  These ones work perfectly for what I need them for.  The little razor thing does work but not for a beard or anything.  Just a few hairs that women often get I guess.<br />Anyhow not sure how the rest of the stuff works but love the tweezers :)
