It says in multiple places that this is not for home use.  But, I'm using it at home and I'm consistently getting 1-2 bars of service when my phone used to say no service to 1 bar  indoors in my apartment.  If I stand near the window where I mounted the antenna I can get 3 bars of service.  I'm pretty happy with this because it lets me make and receive phone calls without having to go outside.
