Just had the smoker 3 months and original still works. It's developed some condensation inside and I know there can be a difference between dome and grate temp but seems like as the temp goes up the difference between it and the Maverick can be as much as 30 degrees. Got hit with a crazy thunderstorm last weekend in the middle of cooking 4 slabs of ribs so the Maverick went in the house, would like something more accurate for a backup.
