My Experience:
1. Installation and commissioning - takes about 10-20 minutes and is very easy thanks to its own setup application. You just have to connect the device to the mains and follow the setup application.
2. Operation: since about a week runs smoothly.
3. User Interface - no special ergonomic but at least, you deal with that. Reboot a bit slow but not (yet) disturbing.
4. Removable antennas: I have installed two antennas 9db of Alfa.
Conclusion: it shows the Cisco Relatives. It works flawlessly.
