I first bought the mini, purely for testing reason and due to lower price level. Well that was a mistake. The mini is rubbish. Such a pain, the switch on / level changer button gives up very soon and kid not yourself there is no customer service. Neither cult beauty nor nuface reacts to multiple complains. However this device has separate buttons for switch on and level changing therefore risk is lower that both gives up. If you made up your mind to buy nuface, buy this one and not the mini. The regular usage does make a difference on your face.
