We don't have those brands here in Australia (as far as I know), so for me it was more a demonstration of what 2 part epoxy will stick to. Also, I think you should test these after 24 hours.
All the connections, which are OK in 4-6 hours, are simply better within 24 hours. As to the rest ones, - the time will not help them, as the epoxy glue is not applicable, for example, for ABS plastic. But I was surprised that all the glues work well with metal.
