Title: Save your money
Review: After buying these from a local store, we found them to be a total waste of money. At least we had the chance to return them for full credit. We tried them in the Blackberry and RaZor phones. Each time, no difference in the reception level. If anything, service level went down after entering the building more with this installed. So folks, save your money does not work.Edna
