I have been using super glue from many brands to build model airplanes for over 30 years. From everything I have read, most of the stuff comes from the same source overseas. Manufacturers list the point of origin by the most expensive element of the product, in this case, the bottle. I find quality is more affected by age than by brand. Heat and humidity will mess with the glue. As it gets old, it gets thicker, which helps fill the gaps you should not have tolerated, but hinders the penetraion that you need for a good joint. To make your CA last longer, keep it in the freezer.
