Yup, we're a hub home for Vivint (we started last fall). It's been a pretty seamless experience and we're super pleased. Speed wise, we consistently get up 90 MBs up and down. They give you a really nice wireless router for your home as well. Good, consistent connection too. Frankly, we couldn't be happier and you can't beat $0 for cost.
I wouldn't hesitate to do it again.
