I have heard nothing but great results using Wilson Amplifiers products. These are fully functioning, safe, and legal-to-own products. I know that emergency response vehicles use their products as well. i ordered the most expensive, but you dont have to. they have cheaper models as well. here is the link to the one i have coming: www.wilsonamplifiers.com/weboost-drive-4g-x-cell-phone-signal-booster-kit-470510/
expect a full review, and test. i will post details on here, as well as in-depth videos on my youtube channel: www.YouTube.com/ImStricken06
