Not yet. But when my AQ probe with the melted outer sheath finally quits, I'll be explaining to them in detail why I'm not spending $90+ for the same piece of garbage. The only "advantage" of the AQ probe is the ability to go to 140 degrees "holding" temp setting automatically when the probe temp setting is reached. But the AQ is so well insulated and air tight that it doesn't cool down very fast at all, so this "advantage" isn't worth much.
