The device came quickly, for 12 days from the moment of order. The device was already charged, so i tried it at once, on the aloe vera gel. On the internet i watched the video of use. There are two types of care-standard and lifting, the first lasts 5 minutes, the second-15. Long press the button-on-off, short press-switch modes. The levels are sensitive even on the easiest mode. In one place even felt a slight twitch of the muscle. The device turns off itself after 5 minutes of use. If you did not have time to process all the places-you can again turn on and use. After the procedure, the skin blushed and clearly tightened. The eyebrows clearly did not rise, but the muscles "made noise". The device is supplied with usb charging, after the procedure connected to the laptop. The instructions recommend to use at least 5 times a week.
