Bought 3 in 2017 for a new office install. After half the ports were punched down started finding inoperable ports (did not pass basic tests) that turned out to be defects within the patch panel blocks. Wasted time re-punching several cables before having to admit multiple ports on each panel in different locations just couldn't be made to work. Do not purchase these - there are other choices now.
This product proved to be as unreliable as it was cheap. Half of the ports doesn’t work and the other half loose connectivity when the cable is moved slightly. Anout 15 seconds after punching cables down I noticed that the cables had risen slightly out of the cradle thereby loosing connectivity. I highly suspect this is a CAT6 panel that was labeled CAT6A. Had to throw it in the garbage and buy another from a reputable manufacturer.
