A phone that silences other phones
This is the best example of irony we’ve seen in a long time – a jammer that looks like a cell phone jams other phones! Simply power on The Phone No More and within seconds, all nearby phones will lose network signal, allowing you to:
watch a movie quietly
Dinner at the restaurant
hold productive meetings
Provide an Effective Presentation
Uninterrupted attendance at worship/mass
Focus on the lesson being taught
Spend some quiet time in a museum or art gallery
Read a book quietly in a public library
Stop students from cheating via text messages
Once you turn off the jammer, all phones automatically re-establish communication and provide full service.
