This is a professional-grade 40Khz cavitation machine. Includes: - Cavitation - RF Radio Frequency for Body - RF Radio Frequency for Face - Vacuum Head The two RF wands also emit red LED light during use. I purchased this after spending a considerable amount of money searching for a machine with professional-level cavitation and simultaneous LED output. However, I couldn't make it a habit and it's been sitting unused, so I'm selling it...(T_T) I've used it about 3-4 times. The RF for face was used once, and the vacuum head is unused, so the main unit is in very good condition. (As shown in the fourth photo, there was a line-like print on the logo from the time of purchase.) All heads and the main unit have been disinfected with alcohol each time. If you'd like, I can include a partially used, dedicated gel. Please let me know in the comments. A simple instruction manual is also included. Both the manual and the machine are in Japanese. I'm hesitant to sell it, so I may remove the listing. Please don't hesitate to purchase if you're interested m(_ _)m
