With today's cell phones can you be a kind parent or kind teacher and still be effective?

The Personal Cell Phone Locker is helping teenagers to put down their cell phones, one cell phone at a time.

If you need a teenager to get to work then lock the cell phone upright and the cell phone locker becomes really irritating for the user. But the cell phone can still be used and kept with the teenager.

Or lock it to something so you know exactly where it is. 

If the teenager is still not getting to work then flip the cell phone around and completely lock it down.

Note: Only the Cell Phone Locker is provided, other items in the images (such as locks, chains, wires and cell phones) are for relevant display only.
