This vibrator keeps what it promises. The 7 vibration modes provide definitely for fun. Unlike other silicone vibrator, which I had previously, you can feel the vibration here even at the end of the toy. The material is pleasant and does not smell toxic. Whether the device is turned on, you can see by the blue illumination of the buttons. I was surprised, however, but with the size of the vibrator, I had imagined a little smaller. Overall I am very satisfied so far. I am curious if he remains well in the long run.
