Features
1. 1MHz Ultrasonic(Vibration: 1 million times/sec)
With the safe, special design of touched control panel, there are 8 intensities to induct ions deeply into any kind of skin. When without contact with skin at 5 seconds, the ultrasonic head will stop outputting wave (but the time is still running) avoiding any over heat and burnt out.
2. 3MHz Ultrasonic (Vibration: 3 million times/sec)
There are 8 intensities of inductions for inducting negative ions superficially into any kind of[...]
