I have friends that have the UV-5R and it works well and they are not rushing to change, but I have the UV-82HP and when both radios are together the 82 did receive and send to another radio further away that the 5R did not even pick up. So for what ever reason it might look similar inside the 82 performed a better, it was worth the extra few bucks. I believe the 82 is 8 watts , not 10, have to double check
