Pros: Works up to the advertised 30 feet. Works on most phones in US. See cons for more details.


Cons: Seems to have a lesser effect on older phones. The newer phone read the extra signal and cause a false "no service" reading very quickly whilst the older phones do not seem to care. I have left it on next to a friends phone that was basic and at least 3 years old and it lessened the signal, but never lost signal. The antenas are easily broken as people have said. By simply carrying it in my pocket I snapped one off. I simply unscrewed the housing and took it off altogether as it was not the one for my country anyway.


Other Thoughts: The power and effectiveness drops off expodentially as it is used. You can knock out service to most phones within 10 seconds and up to 30 feet away while fully charged. After just a few uses though of mere seconds you will notice the time taking longer and longer. I totally reccommend this product still though! I bought a second just so I will always have a fully charged unit.


Bottomline: Great product. I own 2 already and will get a 3rd soon!


Perfect as a phone blocker!

Pros: Does exactly what it says!
It blocks incoming and outgoing phone calls, and even SMS:s. The range is quite good!


Cons: The only cons I can think of is that the battey's life isn't that good, and it's easy to accidentally power it on when having it in the pocket, and therefore draining power.


Other Thoughts: The easy-access of the button can be fixed with a little ring and some glue/tape, so one need to use the nail to turn it on.


Bottomline: The range was better than I thought, and it goes through walls without any troubles, takes a time to start working though, a couple of seconds after it's turned on until it interrupts phone calls.
It's really great to use as a prank with friends (good friends), or use to avoid disturbing calls.
Watch out though, the use of this device might be illegal in your contry, and that's up to you to check!
Great product!

Pros: Very small, so can be quite easily hidden if so desired ( fits in the palm of my hand)
reasonable battery life


Cons: The only minor issue i have with mine, is that the battery charge light doesnt always go out when fully charged !


Other Thoughts: From reading other reviews, it seems as though the operating range is somewhat variable.
I've tested mine where i work in a fairly large lab ( over 30ft) and it kills all phones in under a minute.
I've had a look at the output on a spectrum analyser, and the tuning seems pretty spot on for the UK, so i dont think i'll bother adjusting it , as it works good enough for my needs !!


Bottomline: For £20-00, this is the cheapest cell phone jammer anywhere on the net, buy it, you'll love it, but please use it responsibly


Great fun but range is no more than 4 feet

Pros: Never laughed so much using it down the pub. Easily fits into back pocket of jeans and very discrete. Kept turning it on and off: One bloke thought his girl friend kept putting the phone down on him, another was so angry his phone kept dropping the call he nearly smashed it up on the bar. No one guessed what was going on.


Cons: It's range is no more than 4 or 5 feet. If an upgraded one comes out with say a 20 foot range that would be much better. It's so much fun using it easpecially when people are drunk and getting so upset with their phones you could be in danger of laughing to death!


Other Thoughts:

Bottomline: Very good value, good build quality and works well. Kills all the networks in the UK.
