It is STRONGLY advisable NOT to buy any Kutchina products. Horrible as the product was on design and usability, their service has been nothing short of harassment. My 73-year old mother has not been able to use the product for cooking, not to mention the health and life hazard she faces because of malfunctioning product. In addition, their service people are fully incompetent, and one of their so-called employees even hung up on me rather than bothering to provide me with service. This kind of bad service has been going on for several months. Buying Kutchina was absolutely the worst consumer decision I made. I intend to make a formal complaint about the company to the relevant authorities.
