Pros: So much smaller than I originally imagined! Works just as advertised!
All-Metal Construction. Doesn't feel cheap at all. Works while charging. Can easily be hidden inside a jacket pocket or something.

Cons: None that I've encountered yet. I think that if you're rough with the atennaes, they may snap, but if you're careful I don't see anything wrong.

Other Thoughts: I can't wait to take this out in public and use it in stores... or even use it in my store when annoying customers talk on their annoying cell phones.

Bottomline: Well worth the purchase price. I'm so glad I picked this up. I was worried about Customs in Canada here, but it wasn't even opened nor did it even get held up at all. No problem. :)

Nice Unit

Pros: Will knock out Verizon for a good 30 feet almost instantly! Works well here in the US. Friends are impressed and want one too! Works with all providers that I tried it with.. Nextel,Alltel, Sprint, Verizon, T-Mobile.

Cons: Battery takes a while to charge. About 3 hours!!

Other Thoughts: Well worth the money! Lots of fun to mess with people. Lots of fun for a little money.

Bottomline: Get one!!! Crap! I can't use 500 characters to describe this unit! I've shown this to co-workers and they want one also......Fun to follow people around in the store and shut down their cellphone with.

Great product

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!
