The Satisfy-Her is a 7 1/2" combination of sleek, elegant curves and chrome-like mirror finish. However, the sculptural angles are mere icing on the cake for this multi-function massager. This toy boasts 5 vibrating features; a simple push of the soft black button will cycle through a gentle tease, a stronger warm-up, a soft-soft-strong escalating mode, a constant soft pulse, an alternating soft-strong pulse, and "off". A slight 'spoon' indentation in the tip of the massager is also wonderful for nestling against the clitoris. The Satisfy-Her unit takes 2 AAA batteries.
