1. Superspeed delivery: arrived within 24hrs. 2. MASSIVE delivery box, completely took me by surprise. 3. Boxset was loose inside delivery box, items got thrown around a bit. Luckily, nothing's damaged. resent. 5. Machine was charged already, but I fully charged it anyway, just to make sure it does charge properly. 6. User Manuals and Quick Protocol Pamphlets are available in both Traditional Chinese and English. 7. Easy to use/switch between modes. Tried out every mode, all functioned properly. 8. Heads/Cartridges are a little stiff to remove and plug in. 9. No noticeable feeling while using the Eye Cartridge at Energy Level 3 + 3hz, even around eye areas. 10. I used Energy Level 3 throughout the treatment. Face Cartridge: tingling sensations at 3.0mm mode on Neck + Double Chin Areas and in Dual mode (4.5mm + 3.0mm) on Cheeks. Pinching and needle-like sensations on forehead (above brows) on 3.0mm mode. 11. Treated areas did not appear red or numb. (Except above brows: Redness and stinging sensations disappeared within half an hour.) 12. The Blooming Moisture Gel and the Sprout Energy Mask had a pleasant, soothing scent to them. 13. Humidity is very low lately, so the skin felt dry even After using the mask. 14. 1 Day after time: Face Appears Slightly Plumper, Smile Lines Noticebly Reduced. Area Above Brows Feels Tight. ANGES on the Next and Chin, Although Skin Do Feel Somewhat Smoother to the Touch. [Overall: Never had HIFU treatment before. Very impressed with the product so far.]
