MAGT Portable 5V USB Carbon Fiber Heating Pad - Lightweight Electric Heat Mat for Back, Neck & Shoulder Pain Relief - Perfect for Home, Office & Outdoor Use

I work in one of those offices where the thermostat is hidden behind a locked box and set to "too damned hot" during the summer. So I bought one of these heater sets and fished the heaters through the thermostat air box vents to trick the thermostat into believing it was much hotter in the building than it was.It worked.Previously, everyone in the building agreed that it was always too damned hot. Now, there's a roughly 50/50 split. Half the building thinks its wonderful and the other half of the building thinks its too damned cold.But it's not what you're thinking. Nobody cared that I was messing with the thermostat. The problem came when I stumbled into an office whereupon there was a great debate regarding the newly cold temperatures of the building. On one side of the argument was a menopausal woman who was saying something along the lines of, "I shouldn't have to wear a sweater in the middle of June!" On the other side was a rather buxom blonde who asked the audience, "Can I help it if I'm *hot*?"It was my giggle at that last question that got me in trouble....All that said... the heaters worked great for their intended purpose. The thermostat box is hot and the building is cool.
