I attached a couple pictures of the device itself. One photo of the signal strength standing directly in front of it, and one as far as I can get while still being in the house, about 30 yards away (1300 sq ft home, 1 floor). And finally a few speedtest results to show...speed lol.
Best thing about it, is this device is free. Just call Sprint and tell them you want one, and as long as you are in an "airave area" you get it free of charge.
