I have bought a pair of KD-C1 radios.
Appeared to be a high quality crafted ones - very slim and compact, good durable plastic case, USB or cradle charging, Li-Ion Nokia BL-5C batteries compatible (with small modification), 16-channel programmable via native software (available from Zastone), K-type (Baofeng) port for accessories and programming (not programmable via USB), English annunciation, VOX, Scan, Monitor, accessories included.
Tested transmission range - 2 kilometers (through shrubs and small trees).
Antenna is short and integrated (may be a drawback, but there is almost no chance to break it).
Overall, worth the money for 100%. I'm satisfied and recommend it.
