Fwiw, I’m upping my rating to ‘Pretty good.’ 
I continue to receive a lot of value from the v2/v3 cams, bulbs, plugs and rules I use to coordinate them.
The rating change is due to a ‘sense’ of steady improvement in firmware update reliability, and in their handling of problems that do arise. Also, person detection is miles ahead of where it was, in my experience.
Things are trending toward stability, I think, and that’s not nothing.
