I've got a Ubiquiti ER-X and UAP-AC-LR for sale - both were purchased March this year, so still within their warranty period.
In perfect working order, both the ER-X DC power adapter and the PoE are included. Mounting bracket and screws included for the UAP-AC-LR.
These have been running using PoE passthrough, so the DC power adapter has never actually been used for more than a few mins.
Both updated to latest firmware versions as of today (UAP is 4.0.10.9653 and ER-X is 1.10.8) and reset to factory defaults.
Only selling as the owner is moving overseas. These would cost around $310 new, asking $225 ono. Will ship anywhere in NZ T&T courier for $6
