Important Notes for Jamming Distance: The jamming distances we mentioned on website are for customer's reference only. The actual jamming distance will be varied depending on the signal strength and the use location and if full charges, etc.
Important Notes for Portable Jammers with No Cooling Fan: Do not use the jammer when it is charging, or it will burn the jammer as it has no built-in fan. If because of this factor due to the broken of the jammer, the customer will lose the authority of free repairation .

At the start，I need a small handheld phone jammer for meeting room, but the handheld jammer is even not cheaper than a middle end one while the effect range is small. Fortunately, this portable one is suit for our meeting room very well. Thanks

This thing WORKS. It's quite well made, too. I haven't tested range but it certainly works over at least 20 feet. Didn't interfere with WiFi, either, when I tried it.
The four antennas, that's a very good idea and along with a decent amount of RF power is the reason this thing works pretty well. A good design.
I can't believe how FAST it arrived, too! WOW! Very fast shipping.

I've used this item for more than three months, and it stil works well. Actually I doubted it at the beginning for it is too cheap! But now I think I have to strongly recommend it to all of you guys who are looking for cell phone jammers.
