Maybe if it's a proven design. A foreign-made NEMA-style receptacle of good quality is OK with me.
I have some South Korean-manufactured 110-volt receptacles here at home. While not UL listed, they bear their country of origin's ETL mark.
This gizmo is an unknown quantity. Also, UL listings don't guarantee good quality. It just means that the item's not going to cause a fire or electrocute you when used properly.
Again, look at the 50 cent Home Depot-special receptacles. They're UL/CSA stamped. Would you call them a quality device? I sure wouldn't trust 'em.
