The signal strength is good and the speed is good. That's about it.
The initial installation is quite simple and it all goes well until you realize the double NAT due to the Modem's router is a big issue with some VPNs and when you turn it off, you loose all the advanced functions like security and turning off children's devices.
The app is quite awful. No feedback on resetting network, it lags in status updates, freezes etc.
The other big issue is that it takes forever to reconnect after rebooting the Modem. Sometimes it stays red.
Overall, if you install it once and it works for you as is, great. If you need to reboot the modem or use poor VPNs with double-NAT issues, you will not be a happy camper.
