It's not clear why this physical object is a better solution to the problem than, say, a window on your screen. Feels like more of a hobby project than something that provides $230 of value.

I know a lot of people who really like things like the Stream Deck. This seems similar to that kind of a concept. I'd probably take the Stream Deck over this though, its a good bit cheaper and each button has a little screen on it. Having some physical knobs is an interesting twist on it though.
