For the price I paid, I didn't expect a top-end heater, but seriously? Broke after 6 days? Don't waste your money. Performance Broke - what's more to say? Ease of Use The controls are really foreign, but aren't exactly intuitive. When you press the power button, it's in "full on" mode. It's only temperature controlled after you press the up/down buttons to set the temperature. Durability Uh.... broke after 6 uses. Not durable at all. Design It looks good... that's how they sucker you in to this piece of junk. Safety Not sure on this one, but given the build quality, I'd be wary of leaving this on without being fully awake and aware.
