New Wave guessing 4-5 years+. Died. Time flies so perhaps longer. Kitchen gadgets don't live forever. Paperwork says 2017. So searching for another. Best Buy has an Insignia 5 quart stainless steel in route. On sale almost half price at $59.99. Free Shipping. Same unit Amazon and Walmart quite a bit higher in price like not 119.99 normal but half tank gas higher.
