Well just a little update on mine. I'm currently smoking a pork butt and this morning I ran into a small dilemma with my igrill2. I stepped inside the house and was just out of range on the other end of it, and my probe disconnected from my phone.. Now normally, it reconnects when I step back in range. However this time it lost all signal and was unable to reestablish any connections. I tried restarting the app, my bluetooth, and my phone. I even turned the igrill2 off and on.. Nothing. Slightly annoyed by the inconvenience I called up the company, and they told me to try taking the batteries out and hitting the reset button (duh! I forget about those nice reset buttons on electronics..). Luckily, that did the trick, and it even saved the cooking data from the past few hours! Unfortunately I've run into the problem a few more times today cooking, so I've just made sure to keep my phone in range.
Other than that, I still love using the igrill2. And the customer service was great, helped me quickly resolve the issue.
