Product review (1 stars): Failed in less than a week.
Device failed in less than a week. Looks like the thermostat on it has failed. Device always had more than 4 inches of space on every side. Unplugged it for an hour and then plugged it back in and the error cleared and it started to work and then another couple of hours later it had died again. Tried to contact the manufacturer with no success. Luckily I can still return it to Amazon since it's been less than 30 days.
