Easy Heat - Infrared Poster Heater

I bought the "Easy Heat - Infrared Poster Heater - Butterflies"

DO NOT BUY THIS PRODUCT!! DO NOT BUY THIS PRODUCT!! DO NOT WASTE YOUR MONEY!!

THE ‘HEATER’ DOESN’T HEAT UP PROPERLY, YOU HAVE TO TOUCH THE POSTER TO FEEL THE HEAT. I BOUGHT THE ITEM AFTER TAKING COMFORT THAT I WILL BE ABLE TO RETURN IT IF IT DIDN’T WORK PROPERLY (’30 DAYS HASSLE-FREE’??!) - TRIED TO RETURN IT BUT WAS TOLD IT CAN’T BE ACCEPTED BECAUSE I HAVE USED IT?? HOW WILL I KNOW IF IT WORKS ON OR IF I DON’T PLUG IT??
