I love getting direct feedback on the temperature of my grill and of the meat being grilled.  The app was fairly easy to connect to the wifi.  The wires are wrapped around a convenient plastic square.  Pay attention to how it is wrapped if you want to keep it at a tight uniform package, otherwise it will unspool.  

I used the temperature monitor to get the read on the ambient temperature of the grill because the ribs  recipe called for a steady 200 degrees.  This was the first time that I was able to really control the temperature by reducing the flow of propane and turning off burners and keep it at an even temperature for the three hours of grilling.
