I've owned the iGrill and iGrill 2. I don't have any issues with the device, but the probes supplied by the manufacturer (now Weber) are inconsistent. I received 3 new probes recently and each one delivers a different temp with as much as a 15-20 degree gap between them. I reached out to Weber and received replacements. Same thing. What other digital thermometers are out there which have an accompanying mobile app for monitoring temps wirelessly using your phone? Thanks in advance for the advice.
