My use: Separated by a floor and a 10th of a meter, I announced a signal (measured on the router interface) identical to any of my other devices (Wii, Netbook, S3, Squeezebox ...) wifi connected to the same location so distance equivalent to, or even slightly better with this key.
So RAS
17 Jan 13: I realize the use that key captures very well and much better than any of my existing equipment despite its small size, I'm pleasantly surprised. I think I'll order a second.
