Want to make sure your dinner is going to be uninterrupted by cell phone calls or text messages, no matter what, guaranteed? Well, you can turn your phone off, but you can't count on your guests to follow suit. You've gotta take matters into your own hands on this one.
Just grab one of these portable cell phone jammers from Brando. Sure, it's pretty illegal, but it'll block any phone from being used within 16 to 33 feet. Bring it with you to the movie theater to ensure no one disturbs you, bring it to the bar to keep people from talking loudly near you, or just carry it around to enjoy a bubble of peace and quiet. Just don't get busted with it; it'd be a pretty dumb thing to go to jail for.
