The most popular are those that can be worn around the wrist

Vibrators come in many shapes and sizes. The most popular are those that can be worn around the wrist, like a watch. These popular vibrators allow you to control the speed of your vibrations using buttons on the device itself or through an app on your phone.There are also remote-controlled vibrators that allow for more flexibility than app-controlled ones because they don't require any additional hardware on your part (just make sure there's good Wi-Fi coverage in whatever room you're planning to use them). If you want something even more customizable, some people prefer manual controls over those offered by an app because they have more options available when it comes time to adjust their settings or patterns--and they don't need electricity!
