If Tiger or Lulu is the right kind of intense throbby vibration, but you prefer your stimulation to be external OR internal, Volta is worth considering. Volta has the same power controls, high-grade silicone material, and rechargeable energy source in a completely waterproof package. The beauty is that you can experience the flicking of the two tongues for external or internal play. There isn't anything quite like the quivering of the silicone tongues to increase arousal and sensation. Try it on genitals (anyone's), nipples, and other erogenous spots.
