I owned the first Blushield products while living in AZ. Two years ago, we moved to TX. From 13 towers to 75 towers around us now. I just couldn't think straight. I suffered ear problems for these past two years while all remedies failed me. It wasn't until I upgraded to this bundle pack, when I was able to think clearer. I was using a headset for my computer, not to brother my apartment neighbors. Well, EMFs transfer thru them! Now I just lower the volume and my ears are fine again. And I can bless my neighbors with my new Blushield products. My daughter was happy receiving my older Blushield set. My handheld from it saved me from sheer pain driving my smart SUV. So I am happy being able to pass it down to my daughter for her car. Just so you know... When we went on vacation living in AZ, my neighbor reported to me that her life when all wrong while I was gone. I felt bad after hearing everything from her. My husband turned off our Cube while we were gone. It had a huge effect on her life. We returned and the mood in her home lifted! I credit Blushield for helping all those who are near its protection. And the Customer Service is wonderful too!
