anyone used one of these?
pretty cheap for a little silence
No FHE but if it works as advertised it is a blessing
and the inventor should be canonized
i think it's cheap because it doesn't do 4g blocking. no idea.
look what else this site has:

Is there one that makes the offender's cellphone a molten blob or explode?

Interesting. Wonder if it works. We have gps trackers in our trucks now..
FYI,
The operation of transmitters designed to jam or block wireless
communications is a violation of the Communications Act of 1934, as
amended ("Act"). See 47 U.S.C. Sections 301, 302a, 333. The Act
prohibits any person from willfully or maliciously interfering with
the radio communications of any station licensed or authorized under
the Act or operated by the U.S. government. 47 U.S.C. Section 333. The
manufacture, importation, sale or offer for sale, including
advertising, of devices designed to block or jam wireless
transmissions is prohibited. 47 U.S.C. Section 302a(b). Parties in
violation of these provisions may be subject to the penalties set out
in 47 U.S.C. Sections 501-510. Fines for a first offense can range as
high as $11,000 for each violation or imprisonment for up to one year,
and the device used may also be seized and forfeited to the U.S.
government.
But damn wouldn't it be nice to be able to shut people up at the movies. My biggest pet peeve.
I believe that those that have been in situations where calling 911 saved their lives would disagree with the use of said device.
I would think that with enough disclamers all over the place and the ability to control the area that is impacted, a device like this would be fine in certain situations.
One of my previous employers leased an office space that was originally used by IBM as a research and development site. As soon as I walked through the door, I would lose all cell signal. This was not done by a jammer so much as by whatever material was used in the construction of the building. It was quite annoying.
Based on the low output (10dBm is low power) and low claimed range (a 30 foot circle), and the proliferation of cell towers/repeaters in most metropolitan areas, I would guess it is significantly less effective than claimed.
It looks like something that was much more effective in 1998 when the blocked signals had just been invented. Current GSM and CDMA type networks are significantly more robust than they were 14 years ago. Just saying.
I can geek out more if you'd like.

i used to work for the company that pioneered that service (way back in 1995).

The molten blob idea appeals to me.

I was gonna say, the FCC usually has no sense of humor about someone stepping on their turf.

yes, i was aware, but with a 10m radius, I doubt it would cause that big of a stink for them to send out the trucks to triangulate your location etc.
i doubt there is much they can do -- practically speaking -- for a very small portable one.

There is any number of cheap GPS jammers on fleabay, I have it on the highest authority that they do work, just plug 'em in to your cigarette lighter and you're good to go. Or so I'm told anyway, I would never condone such a thing.
GPS jamming is bad news. Lots of things you don't even realize use GPS. Cell phone towers use GPS for the time signal they send out, Airports and airplanes use GPS for automated landing. I read an article somewhere that an airport had trouble with their automated landings at a certain time every day, and it was because a truck with a GPS jammer rolled by at that time. The FCC was not amused. Neither was the FAA.
Here is an article I found on the subject:http://www.newscientist.com/article/dn20202-gps-chaos-how-a-30-box-can-jam-your-life.html
(http://www.newscientist.com/article/dn20202-gps-chaos-how-a-30-box-can-jam-your-life.html)
Given the ease and cheapness of all this jamming, I think it's time we looked at other means then.
Pretending the problem doesn't exist is asinine.
I know our SWAT Team has them and has used them in incidents...
The FCC fine is pretty steep..
So, what exactly is the problem?
Cell phone use in public? (restaurant, movie theater, drama theater, on the street, in a car wash?)
Businesses using GPS trackers to monitor (supervise?) their employees' use of company assets? (speeding, taking the long way, unauthorized stops where things fall off the back of the truck?)
I don't fully grok either of those as a problem.
Ushers don't 'ush? Register your complaint (this is a dead parrot!) and sans satisfaction, take your custom elsewhere.
Company wants to know where the truck is? Get a new job, or start your own company and see how you feel about your employees work ethic.
If there is some other problem... please, enlighten me.

Maybe you don't go to movies much, or at least not where I do. The 17 yo "usher" at the theatre isn't going to stop the film and kick people out. The theatre doesn't care about your business, else they would confiscate them at the door.
I'm not advocating anyone do it, because it's illegal but having the theatre actually be SILENT during a film would be awfully nice, esp given the cost of movie tickets going towards $20 each now.

You are correct, sir. I stopped going to movies because I really, really disapprove of the kind of behavior displayed by many moviegoers and the cost. I am philosophically opposed to paying money for someone (or a group of someones) to annoy the living shit out of me in a dirty, sticky, plain gross environment.
I spent the money I save on a decent home theater set-up and now, while I might not see the latest and greatest movie when it comes out, I have a much more enjoyable movie-watching experience. I get to cuddle on the couch (with ONLY the company that I choose) and drink adult beverages. I hear there are movie theaters that encourage my kind of movie-going experience, but I live in BFE. Besides, my audio is better than the local theaters.
I will make an exception for something that I think is worth it in 3D, but those movies are few and far between. If I am going, I'll probably spring the extra for IMAX to really make it worth my while.
My solution works for me. YMMV.
The only advantage, given your setup, I can see of going to the theatre would be the joy and looks of frustration and anger when you switch on the blocker.. then off for a minute.. then on for a minute.. and so on.

Again, your observation is astute.
And as I would much rather annoy people by riding motorcycles... [Dolph]
Now, if I were to decide to run a theater, I would just build Faraday cages into the theater walls. Think steel screen underneath all the soundproofing, carpet, and use metal doors.
And then I would advertise the fact that cell phones don't work inside (after some testing). [evil]
I would get it just and just leave it in the car. When I see people driving and talking on the cellphone (which is illegal Washington State), I would just turn it on to f with people.

much more fun to just tell people you'll kick 'em out in a very embarrassing manner (and then do it):
