Thus far, this device is performing well. However, because I am still in the process of upgrading the network---detangling the original installer's extreme mass and mess of CAT5e and COAX cables, applying shielded terminations, locating endpoints and ensuring termination integrity through testing, labeling cables and outlets, arranging and routing cables into new rackmount in an orderly fashion to new patch panels, and finally making connections to the GC728XP and GC752XP---I withhold full judgement until project completion and everything is "live." That said, there have been no indications to date that trouble lays ahead. Fingers are crossed!
