OPT脱毛機ハンドピース撮影はビデオを調整する

For AU-S500 OPT hair removal machine and Au-S200B, they can shooting very fast. This OPT machine is better than the IPL hair removal machine. Please watch the video, I adjust the frequency at 1, it mean one shot by one second, it shoots like a musketry, and if i adjust frequency at 10, it mean 10 shots in one second, just like a machine gun.
