This is a best-selling EMS machine model. It is equipped with the world's first "Twin Program Twin Timer" function and an EMS (muscle wave generation) function that burns fat through muscle exercise. It features an EMS mode specially programmed for the waist to thighs. By using a wide frequency band (1Hz to 200Hz) program, it can handle everything from fat softening to body line tightening. As it is a 10-channel model, it can be used for treatment on the entire body. 【Specifications】 Power Supply: AC100V 50/60Hz External Dimensions (Width x Depth x Height): 350 x 280 x 130 (mm) *Excluding pad stand Weight: 5Kg Oscillation Frequency: 1Hz to 200Hz Output Ports: 10 channels Programs: F/L 6 programs Timer: F/L 30 minutes each Modulation: 100Hz/200Hz I think it's in relatively good condition.
