Review: good - it was a good product did the job it was designed for
Review: Didn't work on my phone - Very cheap. I put two on and I still have only 2 bars. The reception is awful where I live. Wasn't expecting much of a phone boost because they were so cheap. Hard to separate the antenna sticker from the paper. Can be easily damaged. Should have spent the money on a real cell phone booster.
