Classic Infomercial - AirCore portable oven

Here's another early-2000s infomercial for a cooking product called AirCore, a domed heating pan you place on an oven to trap heat. Once the AirCore is heated up enough, you simply remove it from the oven and let the trapped heat cook the food inside. I don't recall ever seeing this showing up in stores, at least where I grew up. I wonder if the AirCore actually worked as advertised? Features a brief cameo from Mick Hastie, who would become more well known for his appearances in those infamous Magic Bullet infomercials. He also appeared in an earlier infomercial for the Red Devil Grill, which was later recalled due to possible burn or fire hazards.
