DO NOT BUY THIS PRODUCT!!!!!!!!!!!!!!we used ours once and the first time was okay. Used it the second time and smoke started rolling out of the top of it, the cord got hot, and the whole office reeked of electrical fire. I burned myself pretty bad getting it out of the building...all for amazon to tell me there's nothing they can do to refundand return the item. save your money and buy a product worth while.
