if a quality power cord can improve pic quality, then i wanna try it on my microwave oven.. maybe it will warm up food better and retain the moisture of my kaya pao when i reheat it

i want to know too bro.. but like i said if u say it can improve contrast or black level of your tv then i might wanna try 1 on my microwave oven n see if it cooks better or use it for my hair dryer to see if it gives more volume or body to my hair:)
