I bought this epilator there one month (2 sessions) and I already see the effects. Unlike a previous review this device only works on dark hair and white skin like all epilators forced air. The only gripe is the multiplayer mode when using the unit wane pauses regularly as it heats. For the moment I did two sessions half legs, underarms and bikini and the bulb is always active so it allows several sessions. Happy with this purchase because the traditional hair removal caused me a hair regrowth under the skin and shaving cuts provoked me because grainy skin. Now I hope a long term permanent hair removal.
