I have used Overstock for over 10 years and over the years have only 1 neg review until this !! I purchased this to use instead of my gas cook top--I wanted to have control of the cooking tempature and this said it did, Well it does not work. But I am so frustrated with the warehouse shipping error and it going to someone else first ! Overstock customer service was so awesome --they re- issued it to the correct address and I finally got it. Well , I am very displeased. The thermostat does not work well--it is either hot or off. I am so tired of being on the phone with this order that I will just keep it and give it to Goodwill. Dont waste your $ get a better brand. From the pictures it appears that it is deep and it is not. Its only like 1-inch deep.
