The base of the iGrill 2 is magnetic. To test the strength of the magnet, please try placing the iGrill 2 base on top of the magnetic probe wrap. If your iGrill 2 magnetizes to the probe wrap, then the surface you are trying to stick the base to is not an ideal magnetic surface. Please use the magnetic adhesive disc, included with your purchase, to create a mounting point for your iGrill 2.
Please remember: The iGrill 2 base is not designed to withstand high heat exposure and it must only be mounted on a cool surface. If the surface is too hot to touch, it's too hot for the iGrill 2!
