Yeah, while it "can" I def would not consider low n slow something to do often on that unit, though they did show it doing a brisket and pork shoulder last week.
The next high temp cook would result in a pretty good fire I would think. That said, Rectec did specifically address fires in the bullseye a few weeks back during a livestream. They said the fires they had, the grill was no worse for wear afterwards, they built it to take the heat/fires. I do not know if they just let them rage and burn out with top open, or closed or is they tried to douse/control the fires at all.
The grease even from only hot grilling is a concern of mine, and about the only one giving me pause on ordering one of them. I know how nasty the "diffusers" in propane rigs get from grease of of burgers etc even at high temp and then rust. I am wondering about longevity of the firebox cover in the bullseye
Lack of automated temp control and grease tray as mentioned make low-n-slow problematic at best imho. This unit was really designed to be a "gateway grill" to get gas and weber kettle guys entered into the pellet grill arena.
