For myself, this item was not worth it. The vibrations from the included bullet were not strong, although it could be easily replaced by a bullet that you already own that is better quality. The downside to that however, is that the material is quite hard which made it uncomfortable for use. My partner also said that it was a little tight on him, so it made his experience less enjoyable.

It is a cute,interesting ring that's fun to test out. I didn't like it enough that I would bother replacing the 6 LR batteries when the battery life is up. So for me this is a fun while it lasts kinda toy for me.

At first, two bullets in a cock ring may seem attractive. However, the problem of finding a comfortable way to position the Diving Dolphin, combined with the hassle of finding the right rhythm function during sex, makes the Diving Dolphin a difficult addition during intercourse. However, the bullets are water-proof and can be removed from the ring and reused for other purposes.

The Diving Dolphin is an interesting concept that won't work for everyone. My boyfriend stayed neutral on it, but mentioned he didn't feel the vibrations until after he had an orgasm. I first felt the large bullets ram into me, and then discovered they moved on their own accord to the side. The dolphin didn't act as a tickler. Overall, the toy was fun and a nice alternative to holding a vibrator while having sex. I am not sure I will be buying 6 more LR44s, though, when I run out.
