It was a long time ago, way before the Weber iGrill2 came along, when I first heard about probe thermometers. It was on Alton Brown's cooking show, "Good Eats", when he recommended probe thermometers. I've been using them ever since, and I've been through lots of them, expensive ones, cheap ones, and even remote control ones. But the best one I've had so far has been and continues to be the iGrill2. I've been personally using it for over a year. It's a great Bluetooth probe thermometer for grilling, smoking, or even roasting or baking in your oven. I use it all the time, and I would buy it again in a heartbeat.
