Plug and play, no sophisticated set up.Anyone can use it, uses power from the iphone or ipad. Save money from getting an mp3 car player. However, Radio frequency will be affected in tunnel.
Have been bringing it ard when i'm travelling.Very light small and portable. Good for use in hotels without wireless. Save alot of trouble for me by setting up wireless signal in the hotel room. And also good for macbook/netbook users without the RJ45 port.
