Input:
I bought this radio to use while riding my motorcycle with other riders.  I also purchased a headset to wear while wearing my helmet.  This radio system worked perfectly for what I needed (just to communicate with other riders).  It comes with a 12v cigarette power cord to power the radio without batteries.  I had used it several days on regular batteries without any issues.  I would highly recommend this outfit for motorcycle riders without factory CB radios on their bikes.  Between the radio and headset, I invested less than $50.
