  1. Perfect product used in the schools Review Rating

    Posted by Judy Keegan on 9th Jul 2020

    We purchased these units to use in our small high school, where cell phone usage had grown rampant. Once we installed the units, the change was instant and remarkable--none of the kids had service in our classrooms. They even asked me to turn on the news, thinking some sort of disaster had occurred! As a result, kids are focusing better and are much more productive than before. We have four classrooms at our school, with old-style masonry walls. Each unit is able to completely block cell phone signals in two connected classrooms and another 20 or 30 feet outside of the classrooms. There are only two small areas on our small campus where kids can text and make phone calls. They don't like it, but the teacher sure do! Thank you for a great product and great service! Speaking of service, this company is very trustworthy-- A+

  3. Great!!!! Review Rating

    Posted by Mathiesen on 26th Dec 2019

    Great product, best I can say is, when an abusive cell phone user is with in your hearing range, no longer is there a problem. Anyone outside your hearing range then your just hunting. I carry this product all the time and I can take out almost anyone. I did come across a couple snags where some phones did not get zapped. I bought the next level up, the listed high power without the GPS, I have no GPS issues. Great customer service, delivery (Canada) worked great !. I have to keep low. I carry both zappers and let me tell you, this small one takes out almost everyone in my circle, I am in control now.
