If it takes a while for you to ejaculate or you're just looking for something for more intense orgasm, than you're looking at ideal product. You put it on you exactly as it is on one of the pictures: the ring is attached to the dick, balls go into the silicone, you turn the vibration and the feeling of pleasure starts.
You can use the vibrator separately as well. Has one style of vibration, works on LR44 batteries that are included and you can get them anywhere whenever you need to change.
