I'm looking for a cell phone signal booster. I am hoping someone out there can help me, I have done a few searches but I have no idea what the differences are between each brand and model. The words are like gibberish to me. I want a wireless one (that I don't have to connect my phone directly to.) I have Verizon. I'd also like to keep it around or under $200, but quality comes before price. Thank you.
