Seems to work
we have decent reception outside of a metal building but had none inside until we installed this thing. We have two bars outside and three inside now.

Provides Excellent Cell Coverage in our Barn
I used have 2 or sometimes only 1 Cell power bars when working at the barn and the adjacent paddocks. The zBoost Xtreme brings the reception to 4 and sometimes 5 which is as good as it gets. It gives Spouse and me a sense of security, knowing we can call for help - and take family calls whenever we're in the fields.
Happier Lad.

Unable to secure antenna in place
I was hoping that this would work as we live out in a rural area. I couldn't even attach the external antenna to a pole because one of the screw holes were off center.
We tried it temporarily with one person holding the antenna on the roof while another checks the modem. We tried multiples spots on the roof and we could only get one bar on our cell phones.
I'm driving 60 miles to the nearest Bestbuy just to return it.
