BOB gives parents total control over how much time their children spend with TV, computers or 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 appointed 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. However, numerous BOBs may be purchased and simultaneously used at once. All computers, video game systems and television types are compatible (plasma, DLP, LCD). Ideal if seeking a very unique and useful parent gift.
