We aren’t sure why you would want to block all cell signals in your home. Maybe if you are a super villain or a spy this would come in handy. Maybe you just want people to stay off the phone and focus.
Anyway, this cell phone jammer is disguised to look like a generic painting of some boats. People will just think you buy crap art and they will stop visiting you because you live in a dead zone. It will cost you $150. Hey, art uglier than this costs a lot more.
