The Contour M by JimmyJane is the well known sensual massager that resembles the crown of a molar. It's light, and sized perfectly for just about any hand. It's great for people who are new to massage, and people who've been making massage a part of their relationship forever. It's versatile, being usable as a sort of base for the Contour I and Q, if you can get past the noise. And it gives an excellent massage all by itself.
