I bought my oven a week ago. I've used it twice on frozen foods and both times it took more than twice as long to cook as their chart showed. I called Thane and they said the heating unit was defective and I would have to pay $39.99 plus shipping because I did not buy the unit directly from them (I bought it direct from Get Organized and probably would have bought it here except they had it on sale for $79.99). Buyer beware - the manufacturer does not honor their 1 year warranty!
