Oftentimes, I hear people ask me this question when they see my product:
"Aren't cell phone blockers illegal?"
"No (sir/ma'am), that is a cell phone jammer. A cell phone jammer sends out signals to interfere with other people's devices - potentially blocking 911 calls in an area, etc, and are illegal under federal law, according to the FCC. A cell phone BLOCKER is a bag, like mine, that enables you to block your OWN phone - it is a hardware version of airplane mode that c
One of the most common questions I get from people interested in Faraday cages for electronics is: "Don't Faraday cages need to be grounded?"
This is a question I've investigated. With the help of technical consultants, I'd like to give you the short answer - Maybe!
It depends on the size. A small Faraday cage will not need grounding You can see this in the videos we show on our site - when our shield is tested, it rests on a plastic bin.
A large Faraday cage may need t
I wanted to post to help all those electromagnetic hypersensitivity sufferers (like me) out there.
Your problem is real - don't let anyone tell you otherwise. It took a SmartMeter causing my leg to twitch and giving me headaches every night for me to realize it.
Here are a few links that show it's real:

Lots of people wonder - "How do you tell if your phone is emitting EMF?"
The answer is easy - watch the phone battery. If your phone drains battery 2x as fast as normal in a purported Faraday cage - you have a lemon.
Why? Because the phone drains battery fastest when it is constantly searching for signal. It searches when it GETS signal - implying the bag is not working 100% - enough to stop a reliable connection, but not enough to stop all signals - giving the phone "fal
I took an even closer look at some of the EMF products out there - some of the claims are ridiculously funny!
Paraphrased: "Doubles battery life, cuts EMF by 97.19%" - a sticker you put to the back of a battery. Too bad the batteries companies never thought of it - they could put on 3 stickers and the batteries on a cell phone could last you all week, right? I can't believe this was actually available. What a scam.
Magnetic pendants that stop EMF - if the pendant surround
I was recently reviewing a number of products on Amazon, now that sales are climbing there - and I realized..."WOW - there's so much scamming going on!"
The first set of products that I saw were the $5-18 cell phone blockers. At first glance - they seemed good. Then I read a few reviews - and they said "these drain the battery fast." That's a huge red light! The phone's batteries shouldn't drain fast if the product really works - ideally, the phone should occasionally attem
