I would argue that Ring is the primary consumer success that the VCs are looking at right now. Everything else is not looking good.

Simplisafe raised the $57m in 2014 and seems to have been able to make a sustainable business without VC money. Form Labs is seemingly (with the rest of 3D printing) moving away from consumer to B2B focus.

I find Sphero/Anki raises surprising and wouldn't be surprised if they had Chinese Funds leading the rounds.
