Query: No longer frigid!

This little heater works very hard to keep my tiny space toasty. I was waking up to nearly-blue toes (not an exaggeration) and resorted to ordering this baby because it was cheap and could fit in my room. While it is by no means the best heater invented and I wouldn't recommend it for large areas, but for my compact space of about 15 feet it was perfect. Turn it on, give it a while to do its job, slither out of the blankets and... no shivers! Quality heater, but keep in mind the size.
