This product really works. I'm doing a lot of camping in remote location and the biggest problem is the Internet. I have Verizon and in the past 2 weeks I was in 2 different locations, NY Catskills and NH White Mountains. I was very surprised before I had 2 bars- 3g on my phone and on rt 16 in White Mountains around Mt. Washington I had no service, zero bars. With this tool is got 4g - 1 bar, I was able to Skype in the middle of nowhere
