I used the device several times, this is my opinion; after using it takes about 2 weeks without shaving for the hair falls, to where the hair fell regrowth has slowed the hair does not grow for about two months but they reject anyway! It works best on hair thicker as the underarms and bikini for the rest it's not working very well and the leg is very long use, the hair grows back thinner than a razor. If using the camera for a long time Level 5 and 4 no longer works but few continue the next day.
