Compare with the cheap rhinitis laser, what`s the COZING-USBN advantages :

1. The imported laser diode, it is the real laser light t-h-e-r-a-p-y , the others is the led light. 
2. High classes wire, not the cheap wire. 
3. Laser penetration is 1-3CM, but led is 1-3mm, so the laser treatment efficiency much better than the led .
