Chuck trying to guess when your food is done to your liking!  These probes can be paired with an App via Bluetooth so you can read the temperatures of the food you are cooking on your mobile device.  The magnetic display can also be secured against the side of your grill or stove.  It has custom temperature pre-sets that will alert you when each of your desired temperatures have been reached.  Four different color probes make it easy to monitor the temperature of multiple items.
