Circle

I've been using Circle 1st Generation with Nighthawk R7000P but recently, I've been having increasing issues with it.

I decide to investigate newer alternatives and I was very surprised at the cost of the newer version. I think protection for children should be built in, free and not at a price that would be prohibitive for many families.

Is it value for money? And can I easily cancel the subscription if I'm not satisfied with it?
