I see $350? If it was $250 it would be a no brainer but at $350 I find myself on the fence as well given some questionable reviews. Conversely, the Eero kit seems to be well reviewed but costs $549 for a base unit + 2 beacons — maybe it will go on sale next weekend...
I find myself in a similar situation where my Wi-Fi needs a little help busting through old plaster and brick walls (not ideal for wifi) but also not wanting to drop half a grand on networking equipment when my current setup is passable (but could be much better).
