BOB gives each parent a unique way to control how much time their children spend on TV, computers and video games. Set up is a simple 3 minute process--plug any device's cord into BOB, lock BOB and plug BOB into the wall. BOB automatically shuts off the television or computer screen the moment your assigned time has expired. You can set up hourly, daily or weekly limits as well as time blocks (example: no TV from 4 to 6 pm). BOB can only be unlocked with your key. BOB can only manage one device at a time. All computers, video game systems and television types are compatible. Ideal if seeking very unique and useful parent gifts.
