I'd like to think that all outlets are "built to spec"
There should be nothing wrong with using the .89 cent socket with the UL symbol.
Except in a shop environment, how often do you plug/unplug an electrical item ?
The only exception would be a high wattage circuit. I had a 1500 watt space heater plugged into an outlet that got hot. I would expect a pricier socket would make better contact with the plug.
