Just take a look at the Echo Silicone Vibrating Dildo and you can understand why it's one of our most popular products to date. It is a multi-speed vibrator without any wires. This beauty has a pronounced head and strong ridges which help to stimulate the g-spot or the prostate area. The flared base gives you the freedom to use this dildo for anal play or to attach to a harness and become a strap-on. It measures 6.75 inches long, 1 3/8 inches in diameter, and 2.5 inch wide at the flared base. To use the mini vibrator, you would need 3 watch batteries, which are included with this item.
