Direct replacement for previous XAV5001 EOP adapters. Work just as well for 1/4 of the cost of previous unit. Very stable, connected across 70's installed power grid and plugged into powerboards at both ends (one of which is surge protected!). Recorded speeds (using netgear powerline utility) range 230 - 360 Mbps (both up/downstream) never less than 210Mbps.
p.s. EOP first recommended to me by BT engineer - some of the best advice ever!
