My OptiGrill+ worked wonderfully for about one month, after which it hasn't worked properly at all. It almost always skips the preprogrammed options, not allowing you to use them at all. Today, the programmed chicken option actually worked to a point, until it just shut off completely, right when I was using it. I then plugged it into a different power outlet, wanting to be able to complete my grilling. It did work, but it immediately sent to the red colour reading, meaning it was very high heat. I think if you get one that works, it's probably great, but mine, I was I could get a replacement!
