Review on Revolutionize Your BBQ Experience: Smart Bluetooth BBQ Grill Thermometer with Upgraded Stainless Probe - Leave it in Oven, BBQ or Smoker, and Get Wireless Remote Alerts via iOS/Android Phone WiFi App by Laura Rodriguez

Easy to use! Just insert the included battery and download the free app. I've used it in my 12 hour smoker (I put a probe and cable through the vent and just put a small transponder on the smoker) and it's held up well! The range says 150 feet, but sometimes it's less (but that might as well be my phone), but it sends an alert to your phone if you lose connection. The application has settings for different types of meat, but I haven't used them since I have my own smoking methods (if I cooked on the grill, I would). In general a good product. You don't have to open a smoker and lose heat, you don't have to go out in the cold, and you don't have to rob a bank in the process!
