Dr. Vibe is the only double-penetration, triple-stimulation wand massager attachment I know about, and for that fact alone it's worth picking up. The clit brush is a smidgen too short, so the anal rattle might be giving you an external massage instead of an internal one---but this attachment feels incredible either way. The material is a mystery, but it carries vibrations so well that you won't believe it until you feel it---there are even two resonant frequencies to knock your socks off.
WOW! That's a LOUD Fairy!
