I repurposed my old 6s and I gotta say the quality is excellent. And the free version of the software has more than enough for most people, so this could very well be a completely free upgrade for someone.

I do have a lifetime license, and have tested it with my 12 pro and while it obviously looks better, most of the time I stay with the 6s and default settings since I can just leave it mounted on top of my monitor.
