This system is fantastic. I use it on the BBQ in the Oven and in the Air Fryer. It sends the temperature in real time and works flawlessly. I don't have to keep taking the temperature every so often to see when the meat is done. PERFECT. Sit relax, put your feet up and crack a beer. The iGrill will give you a heads up when you are getting close to the internal temp you are looking for. It will then signal you that you have reached that temperature. ENJOY!
