Yep... I got it set up and it greatly and instantly improved my speeds.
I'm still not 100% sure what causes the original problems in my house. I think it's a combination of things including netted/steel railings throughout the house, crappy service from Verizon, lots and lots of neighbors on the same service and not enough bandwidth to go around, etc...
Regardless, would definitely recommend. However, I'm pretty sure you need at least 2 "pucks"... one that plugs into your router or modem and another to serve as the spread point.
