Last year, I purchased a #2-plain General grommet-repair kit from Amazon to compare it with the equivalent Lord & Hodge kits.  The contrast was remarkable!  The Lord & Hodge sets were domestically-manufactured and met all of my expectations.  The General set, in contrast, was cobbled together in India and was garbage.  A couple of the grommets were pitted on the margins, and one of the male components was bent.  Two more set imperfectly and had to be removed, a problem which I haven't encountered elsewhere.  I finally got around to weighing the respective grommets and found the General submission to be roughly 30% underweight.  Brass foil.  Although the first commentaries could be considered somewhat subjective, the weight differential isn't.  Additionally, I strongly suspect the setting tools are inferior to L&H's, a rough brinell test having indicated that the anvil material is softer.
