I agree with Jake, save your cash. At 250* or 300* your pellet smoker will hit 275* at some point with the fluctuations in temp. Use your therm to check actual grate temp, not what Pit Boss display says. The ability to adjust in 5-10 degrees increments in not needed for pork butt, brisket etc. You have a good set up, continue to cook and learn with it.
