Reviews show great 5GHz range and throughput, and seems a decent package overall. I posted because in the last week I had received 2 different offers for this via newsletters at ridiculous prices. This seems cheapest I can find and decided to make the jump for it as my G router isn't cutting it.
Also has Gigabit LAN, so its good for wired connections and for densely populated areas with a lot of 2.4Ghz interference.
Sadly, as it has only a single radio it can't run both bands simultaneouosly, but at this low price that's a reasonable compromise - a dual-radio version would need six antennas (three for each radio), and as it uses traditional external arrays it would end up looking like a Christmas tree.
