The Bimini Bubbles G-spot vibrator from Fun Factory is a non-invasive piece of silicone bliss. It is rechargeable water-proof and has a one year warranty. it's unique design, mimicking 4 bubbles placed ergonomically on top of one another lends to both G-spot and vaginal opening pleasure. The handle is the only complaint that I have but it is a powerful 4 vrooms and easy to operate.
