I have only had this radio for a day but so far I know I will like it once I get it all programed to my liking. The manual that comes with it is only good for starting a fire or proping open a door, it is worthless for learning how to use the radio. Luckily there is a good manual here: http://wouxun.us/Manuals/WouxunUS%20User%20Guide.pdf
Power is very good, battery is very good, volume is excellent and sound quality is excellent. I can see that it is a must to program with the cable and software, doing it manually is a pain.
I have found no real fault so far except the voice gets on your nerves, but you can easily turn it off and the beeps when you press a button.
