For me, the Je Joue Mimi Vibrator delivers best when used as a clitoral stimulator, and with the addition of some water-based lubricant. Without the lube the silicone material feels too chafing and draggy over such a sensitive area of my body. The lubricant does seem to heighten the sensations from the vibrations, which are incredibly powerful on top level constant but which still take me longer to orgasm with than my Doxy Wand.
