I was very pleasantly surprised by the masturbator, I thought it was just a traditional vibrating masturbator, but the two main modes are great. One mode sucks hard on the cup and it feels like a vacuum is created, which is really very pleasant. The suction can be adjusted to several linear levels and also has variable suction levels. In the second main mode, the internal sleeve rotates, either slow, medium or fast, as well as quickly changing direction and some confusion modes. All in all, fantastic
