Product was working fine for about 2 months then inexplicably stopped working one day. I followed the manual to clean and maintain the air fryer but there seems to be an electrical problem. I tried to contact the company but their "Contact Us" page has no information on it. Nothing negative against the seller or Amazon service but would not recommend Harbor products if looking for a reliable, long term product.
BROKEN within 3 months - Do NOT recommend Harbor products
