Input:
Great little CB radio but way under powered. I would need to hike most of the way back to safety to get a signal where I could call out for help. I returned it not because I didn't like it but I need a radio that I can rely on in an emergency. If you just want a CB to listen and talk to the truckers on the road, this would be for you.
