Also setting up a Ubiquiti UniFi is an enterprise level product, with all the complexity that implies.
Update: See http://wiki.ubnt.com/UniFi_FAQ#Wireless_Uplink as an example of what is required to setup Ubiquiti's answer to mesh networking. Note that this requires the user to setup server software to do the provisioning.
The many positive Amazon reviews seem to suggest otherwise.
Here's a sampling:
"This was very easy to install and configure and has great coverage in our 3,500 sq ft home."
"As a tech savvy, but non-technically trained individual - this WAP was extremely easy to configure and provides exceptional wireless range and speed."
"I can't say enough how simple the installation process on these has been..."
Note, however, that the Java Runtime Environment is required to configure the software. I guess the dream of the 90s is alive at Ubiquiti.
Running the installer and paging through the wizard.
