Summary: I love, love, love zBoost! I'm in college and I live in a old apartment with concrete walls and floors. I could NEVER get service. I got so tired of standing on my bed or huddled up against the window that I changed my service from Cingular to Sprint thinking it was the service. I had the exact same problem with my new phone! I didn't even know that signal booster devices exsisted. My parents were getting really mad about not being able to ever get in touch with me so they did some research and found the ZBoost. I hooked it up the easy way because 1. I'm lazy and because 2. I can't really rig something to the roof of my apartment. I just put the antenna where I get the most service in my apt (top of a window sill) and no joke, I had gained like 2 more bars instantly. Its so great not having to only call people from the road and always getting texts and voice mails. I would definately recommend this product to anyone in a similar situation

Summary: good we can use again and again.it is good and expensive so that every one can buy it and enjoy its feature because it is very expensive and again i am preferring to this

Summary: For years, if people at my place of work wanted to take or make cell phone calls, we had to go outside. With this product installed, all of our phones went from getting 0 to 1 bar of service to being MAXED out all the time. We are now able to make calls without worry. This is a great product that I highly recommend.
