"No transmissions and receptions of cellular phone calls under jamming coverage area!!"

Everyone knows that sparks occur when you switch a mobile phone on and off. If the mobile phone short circuits or the phone is too old, it is possible to have sparks; since the air in gas stations often has a significant density of the flammable gases, it is very easy to end up igniting gasoline and causing an explosion.

The RODMO Mobile Phone Jamming Device immobilizes the telecommunication connection between the mobile phone and the base station returning a peaceful and comfortable environment to you and also ensuring your personal safety.
