Check the box for plumb and level before you mount anything, that cheap plastic hides a lot of grief.

Funny enough, I used to be the opposite. I was always peeking and spritzing and messing with the vents every thirty minutes like it mattered. Then I did one cook where I just walked away, only checked the probe after two and a half hours, and the bark came out way darker and crispier than anything I'd gotten before. It was a real slap in the face moment. Now I force myself to go do something else, even if it's just sitting inside scrolling my phone, because I know opening that lid is just stealing heat and breaking the bark before it sets. Patience really does the heavy lifting.

Brand new tools failing is just our luck sometimes.
