I assume this is used / returned gear again? I have never any second hand Ubiquiti hardware worth anything.
I guess the switches will be once they are old enough to have a secondary market.
Do you see it with Juniper or HP? I'm happy with refurb, but don't want used with those either (I don't want Cisco even new) but xByte doesn't sell used, primarily, only refurb so effectively new.
