Good for slow cooking, however if you want to sear a steak or cook past 400 degrees, this item is worthless. I use it on my Primos grill (ceramic "egg" grill) which cooks burgers and steaks better at around 450+.
I liked using the Igrill for monitering my pit temperature when cooking low and slow and use the other probe for monitering the food temperature. It worked great about 3 times then one of the probes failed. I called customer support and was told I could buy another one. so now I just use the one probe. It works as advertised and beats getting up every 30 minutes or so to check on your dinner.
