It does feel like the kind of product where everyone involved in the company and most of their potential customers know what it is, why they want it, and how it works.
The ad copy focuses on making it attractive to people who arrive by searching for "BBQ Controller" and aren't sure which one they want. There's no real reason to try to make it approachable to people who don't even own a smoker, it's not like someone's going to impulse buy a $400 gadget to improve their experience with an activity they've never done.
