I couldn't agree more. The Ubiquiti wifi hardware is better than any of the SOHO (Linksys, Asus, etc) I've ever used. I've changed most of my friends and family to using Ubiquiti stuff and I never hear about wifi problems anymore. The Nanostation and Rocket product lines are what I usually get.
I put 4 Unifi's in a friend's large house and it the performance is great.
