The lack of 'precise' control, is not a big concern for me... However I don't understand why they don't have at least a simple timer on things like the hot rod... ( like on most Traeger controllers, the hot rod comes on for a couple minutes as you start the grill, then turns itself off when the timer expires ). It would be nice to have a shutdown mode that turns the pellet feed down to a minimum level for a few minutes while the fan continues to blow, before eventually shutting everything down.
FYI - IMHO, leaving the fan running after the auger has been on high and then abruptly shut off , is probably the worst thing you can do on a pellet grill. Leaving the fan run for a short time, after you've reduced the auger feed for 5 minutes or so could be a good thing, but don't turn the auger off when it's been running on high and leave that fan blowing, that's just going to fan the flames of any burning embers at the end of the auger tube...
