I purchased the SM025 on 5/21/2022. It's been used several times a month with great success. Yesterday (Christmas Day, 2022) I smoked a very expensive 7.76 pound prime rib, this was a prime grade cut of meat. I ordered it from my local butcher without asking about the price - I probably would have gone with choice if I knew prime was 24.99 a pound! Caveat Emptor and all that. - but a frick'n amazing roast.
Anyway, put it on the smoker at 225* at 10 AM. Used about an once of cherry and probably 1/2 once of hickory. Knock the temp down to 140* when the meat reached 220*. This was at 2:45 PM. The roast went to a final temp of 233*.
Medium rare Perfection!
I have been using the unit for a few months and have gained total confidence in it. This was done with zero concern or worry about, well, anything. Family loved the results.
