The ubiquity second port is quite handy if you have IP cameras or something nearby - it makes connecting them up and linking much easier!
I'll throw my name in for the Ubiquity kit too!!
I've got two of the Loco M5's linking two houses together for Internet. One house is being fixed up and it was in LOS to my parents house. I used the 5GHZ band for a good connectiono and it's linked at 270mbps day and night!
Last time I checked, they had an uptime of almost 180 days odd?
The products are easy to configure, good regular updates for security and are a quality bit of kit to install - I like them. The outdoor units have power indicator lights on too for signal strength, which was well handy for aligning them when up on a roof.
