The entire time he was talking I was wishing I had one of those cell phone blockers, also known as cell phone jammers.  I would have loved a cellphone jammers, turning that thing on and watching him drop his call.  To be honest, I might like to have it so I can be proactive and just randomly jam people for kicks.  Imagine having one of those when you are with a buddy who is on an important business call, you keep jamming him, all the while he’s about ready to pop a vein in his forehead!  Good times!

If you are considering a cell phone jammer think about a few things, often walls or even the antenna being blocked inside a purse can keep it from working.  That may frustrate some people who want to keep it completely concealed.  Something else is the range, a few are as low as a 12 meter radius while others have a much stronger signal.  If you are looking for one to carry with you and want something portable you can find 12 meter range products for under $100, while 25 meter range go for less than $200.  If you own a store, or work in a library as an example you may want to consider a mountable version that offers greater range.  Whatever your need there is a cell phone blocker product that will work for you.

For recommendations take a look at the Mobile Phone Signal Jammer – High Powered Cellphone Jammer that works within 20 meters that only jams cell phones and nothing else.  It’s portable and only slightly larger than a standard iPod.  If you are looking for something with greater range and you have the ability to mount it consider the High Powered Phone Blocker Shield that has a 75 meter radius.  Either one of these would be considered a popular gift for a high school teacher in need of a cellphone blocker.
