Well, a few observations now that I've been using my knob for a couple of weeks:
Installation
Installation was very easy. No real issues. It went smoothly and just worked.
Features
First the positives:
- The knob is nicely built and fits very well into the car's interior.
- It works mostly pretty well. There are a few little bugs (e.g. rear vent control doesn't work reliably).
- The UI is nice overall with crisp and easy-to-read icons.
- The commander adds some useful features independent of the knob (e.g. unlock charge port from door handle, dashboard on mobile phone).
But there are a few negatives.
- Lack of sync between the knob and the tesla UI is a real gap and makes temperature and fan control way less useful than they should be. They say they'll fix this, but until they do the experience is much diminished.
- Lack of lighting around the buttons makes use at night time somewhat awkward.
- Limitations of what can be done on the knob vs the buttons is surprising and unexpected. In general, the list of actions on the knob is quite narrow.
Overall, whilst the knob works, it's really not proving to be as useful as I hoped. For the moment, I'm not really using it much, which is not what I expected.
