On the pluses: I like the CTCSS scanner, that is handy when working with bubble-pack radio users. Build quality seems sturdy, range is good, and audio quality is great. I like being able to swap out antennas. Sometimes I even connect it to my large exterior j-pole, and it works great (even though the j-pole is tuned to Ham bands, GMRS is "close-enough"). I like the large channel capacity, including enough space to store every repeater I could conceivably connect to in my region.
On the minuses: The programing software is poor, I wish Chirp would support this radio, as it has a much more polished GUI. I also wish it had FM broadcast and NOAA weather support (this is due to a UHF-only design). I have a KG-UV9P as well, so that makes up for those two missing items (and it also has a flashlight). Ironically, the one thing the KG-UV9P misses is GMRS TX (it can RX it though), so for full coverage, I have to carry both radios. Lastly, I'm annoyed that it uses a different charger than nearly every other Wouxun radio, so I can't share car/USB charging accessories.
