Easy to insert and stays in place due to the tapered neck. That is what a plug should do. It can easily be turned to adjust the electrode placement for hitting the right spot, whether next to the prostate or the G-Spot in the case of  women.  Based on its style and elongated stainless electrodes, it will create many great sensations, from simple constant current to hard pumping action.  It has a hard-wired 2.5mm male audio connection, so you may need an adapter if you are using a power box that has 3.5mm jacks.  

The dimensions for this product make it perfect for almost anyone to use comfortably.
