I know you guys have seen those cellphone commercials with the guy in glasses saying “Can you hear me now?” Over and over again because apparently the service is bad on the cell phone and goes through “Dead Zones” all the time. Ive had personal experience with these kinda phones and I can say from that personal experience that cell phone amplifiers really make a WORLD of difference. So, if you are one of those unfortunate folks whos cell phone goes in and out of service all the time, you really may need to think about picking up something to fix that!
