I'm enjoying my DualFire. I have already cooked on it 5-10 times. The door arrived with a small rust spot and was replaced within the week. Apparently, the probes can be calibrated, and I will do that, as one is consistently 10 degrees or more off compared to my Thermapen. Overall, I'm very happy with the purchase. Good build quality. Easy to use and maintain. Good app (wi-fi, so I can monitor, even away from home). Good customer service.
