Query: cell phone antenna boosters that are not boosters

This product didn't do anything for my phone or anyone else's phone I put it in!!!! I wish I would of never bought this product. My phone had 2 bars on it before I installed it and when I put it in it still had 2 bars on it then it would fluctuate between 2 and 1 bars after I restarted the phone. Then I put one in a government phone and it didn't help either before i put it in it had 2 bars but after I put it in it had no service at all!!!!! I did everything like the instructions said to also!!!! i could give it no rating i would!!!!!!!!!!!!!!!
