What you are not understanding is this is simply a $5 difference,or less, in the quality of a part. Now that I figured out the work around, I can change Temps, set timers, set meat probe alerts all from the comfort of the beach in Florida while my smoker is in cincinnati.One is not going to get a $200.00 temp system/ app with a $500.00 smoker. And even if it were available I would prefer that Masterbuilt put the money into the smoker itself rather than an app.
These are nice charcoal grill/smokers. I haven't had any problems with mine. And even at worst case if I did have some of the issues others are describing I would buy another 560 anyway. Wood chunks with charcoal combined makes for some good smoke flavor and the 560 is amazingly good at maintaining a steady and precise temp. Not so easy to do with charcoal and wood.
