The circle device must be within 10 feet of the router so it's impossible to connect to your neighbors router (assuming your not in an extremely tight apartment situation). You also can't walk into a coffeeshop or hotel lobby and use it. Yes, you can monitor you children's internet activity but isn't that what you should be doing? As far as an open wifi network; you always assume that someone is monitoring your activity. Be security conscious and conduct sensitive business through a VPN.

first, many people have this tight appartment situation. 10 ft is not reasonable, and i really wonder how you can accurately measure that you're 10 ft away from the router, and not a repeater ; which brings me to the 2nd point : yes you can connect to a coffeeshop : not all of them are equiped with open networks + sign-in pages, because those require to pay for it and not all shops can afford that. Last, you can still connect to your work place wifi, can't you? More personally, assuming you share your life with someone, how would you react if you were to discover such a device in your home?

...and NO, monitoring your kids isn't the answer since they can watch porn from anywhere else than your monitored home. I guess something like education should be better than repression?
