This is covered with body safe silicone and it is such a nice, soft material. This vibrator is quite different than others I've tried. This one has a bit of give to it, so it conforms to the body quite well. It includes the standard 7 vibration patterns and combined with the 360 degree rotating head is quite effective. The rotation is nice as it permits the individual to choose the angle of penetration for maximum effectiveness and/or comfort. It also adds a bit of new sensation when used in situ. It's a bit longer than some other units but definitely larger in girth.
This is a great toy at a great price.
