LETEN Spinner automatic masturbation cup

A cup shaped automatic masturbator made by LETEN. It measures 18cm×7cm, with an ABS outer shell and TPE and silicone inside. It moves in two ways, vibration and rotation, and charges over a magnetic USB connection.

It does not only vibrate, it turns

Unlike products where the inside of the cup only shakes, this one includes a rotating action as well. The stimulation runs in a different direction from the up and down stroke of a hand. It is a movement you cannot produce by hand, so it feels unlike what you are used to.

Plain on the outside, different inside

The outer shape is plain, with no decoration. Its form does not announce what it is at a glance, so it draws less attention sitting on a desk. The outer barrel is hard ABS, and only the inside that meets the body is made soft, in TPE and silicone.

Magnetic charging and water resistance

The charging contact attaches magnetically. Since no port has to be cut into the shell, there are fewer places for water to get in. The supplier rates the water resistance as good. On a masturbation cup, where washing is the main chore, that is a genuinely useful combination.

What to know before you use it

18cm×7cm fits in one hand but takes up a drawer compartment. The original listing does not state the number of vibration levels, the battery life, or the charging time. The brand is listed as LETEN of Japan, with production in Hong Kong. Since it has a rotating function, lubricant that dries out produces a dragging feeling, so apply plenty and add more partway through.
