Anyone used AirRave? Does it work?

[Nagual]

I may have to give Sprint a talking-to myself and get them to give me one of these - because reception in my home has gotten so bad that I am now getting massively delayed texts and calls going straight to VMs which are also delayed, sometimes for hours.

I may tell Sprint, look, either you force me to roam (which is included but costs them money and makes my data go down to 1x), install a closer tower/antenna, or give me one of these. Hope it doesn't come to that. Right now I've decided to try a different radio, and if that doesn't help, roaming all the time at home is my only option without an Airave or field work on Sprint's end.
