Very Effective!
by CM
on 07/02/2009: This is a very effective unit - small at less than 6 inches (14.5cm) with the antennas on, so it's very portable and concealable. Whether you're on the train, movie theater, or other place where obnoxious people are yakking on their phone, in about 10-15 seconds, this unit knocks it out completely leaving the caller dumbfounded as to why they lost their signal...in addition to cellphones, this also applies to blackberrys as well.
the construction is very solid and made of metal vs cheap plastic and the pushbutton mechanism is also very solid and direct. There is a small risk of accidentally depressing the button if it's leaning against something in your pants/bag, but that's only happened once to me and just something to be aware of.
I may not use it all the time I'm on the train, but to know "I can if I want" gives me a lot of peace of mind....be sure you know which one to order - there's the portable GPS + mobile phone jammer and this one with broad spectrum (3G)....or at this price it's very affordable to buy both! - I did.

Compact and Powerful
by Matthew
on 05/22/2009: This compact cell phone jammer works great. I have "no doubt" jamming within a 12-15 foot radius! If your looking for a portable jammer, this is a GREAT ITEM for the price!
