I've had one for about 9 months, as long as I've had my offset and it works well. I always use one probe for pit temp and one for a meat probe with an iPhone or an iPad. I also have a maverick wireless and an old school dial thermometer mounted on the pit. To me the best features of the iGrill are the alarm options and the ability to output data to become part of my logbook. I'd get another if/when this fails (or something comparable as technology changes). Now all that said, I'm getting much more comfortable that I can read my fire, watch, feel & poke whatever meat is in the cooker and as long as I'm in my target temp range +/-25*-30* and I hit a safe IT I'm not as anal about temp data as I used to be.
