I bought from the website and have found it not to cook food in their allotted time, but I have found it takes double the time. I cooked a seven pound pork roast for five hours and it still was not done. I cooked country style ribs and the outside was charring before the inside was done. How can this be when "infrared" is suppose to cook from the inside out. It is no quicker than my oven or slow cooker. Now I have to pay to ship it back even though it is not my fault that it does not function like they say.
