2 bars outside, 0 bars inside, all this thing got me was 1-2 bars inside which doesnt solve my problem.

I bought this thing hoping at most to get 1 consistent bar of 3G. We live in a black hole

Had 1 bar in first location and it boosted to 2, as advertised

Surrounded by timber, and if the stars aligned perfectly we may be able to get a bar of coverage long enough to check our Facebook

no bars, no service, drained phone battery in half a day
