    If you find yourself checking your phone first thing in the morning, if you find you're text-messaging while driving, checking your phone instead of working on an important assignment—you are addicted.

    Don't worry. The new NoPhone might be just the thing you need. It looks and feels exactly like a smartphone, but it does nothing. It's just a piece of plastic that you can carry around in your hand to fool yourself.

    NoPhone is currently a prototype(手机模型) that will cost only $12 once it hits the market. Its makers are trying to raise $30,000 in order to cover the production and marketing costs.

    Dutch designer Ingmar Larsen, who helped create the NoPhone, said that he had the idea as a joke along with his friends Van Gould and Ben Langveld. To their great surprise, the idea received a lot of attention online and people from all over the world started placing requests for NoPhone of their own, so that's when the three friends decided to raise money for mass production.

    David H said,“ I used to sleep with my phone in my hand, but my night errors would cause me to throw it across the room in an unconscious panic. With the NoPhone, I can still enjoy the comfort of holding a phone in my sleep, without waking up to a shattered screen, thanks, NoPhone.”

    If you're interested in NoPhone, but concerned about not being able to takeselfies anymore, don't worry. The makers do have an update at no extra charge—the mirror sticker. That way, they say, you can enjoy “real-time” selfies with your friends when they're standing right behind you.
