I use both legs to the bikini line and underarms. Frankly if you're used to an epilator is by far the least painful. Side efficiency is formidable. It is very fast (about 40 min for two whole legs + bikini + underarm). It cuts the hair very little profit compared to my old epilator regrowth is slower. The light is also very useful.
Too bad it does not work anymore after a year ... (my previous lasted for years)
