The booster works great.

Returned the product and still looking for a better booster.

After purchasing a cheaper cell booster and discovering it was worthless I decided to try this unit

My house blocks reception; T-Mobile will give you a free signal booster, but it's only for indoor use

What good is a signal booster if I can't even make phone calls?

I would highly recommend this cell phone booster!

The booster has 4 LED's and all should be green with NO antennas connected.
