The Blue Dolphin vibrator/dildo combo is probably one of my favorite toys I own. It has so many different speeds/functions that it can keep you on the edge of orgasm for as long as you can take it.
This vibrator is meant for Vaginal penetration, and clitoral stimulation. The rotating ball bearings inside the shaft stimulate the nerves inside your vagina for an extra touch.

This toy is fun enough to share the experience with a partner, or for solo-play.

The Blue Dolphin is made of Jelly material. It has the typical Jelly feel, but is very smooth, and 'squishy' for the lack of a better word. There are large vertical ribs on the shaft, and the head is very large and bulbous. The material of this toy is very porous, so sharing wouldn't be recommended without using a condom.
When this toy first arrived, it did have that weird plastic smell, but a quick towel down with a wet washcloth took some of that smell away.

The Blue Dolphin is a pretty hefty toy. The total length is 7 1/2 inches, 5 inches which is insertable. The 5 1/2 inch diameter makes this a pretty good hand (or vagina) full!
This toy is blue and clear jelly material that is actually very pretty. The best feature on this toy though is that cute little dolphin hanging out hear the bottom. That cute little guy will bring you to one of the quickest and fulfilling orgasms. The vibrations on this toy are situated directly under the dolphin, so they are very strong, and do not quit! You could even turn the toy over so its not inserted and use the back of the dolphin to rub on your clit and still feel the super strong vibrations.
The size of this toy is not for the faint of heart. As I said before, it is a pretty good size.

The function of this toy is what makes it great. It has a very large battery pack (takes 3C batteries!) but it has 2 slide controls that control both the turning of the ball-bearings and the intensity of the vibrations.
The swirling and twirling of the ball-bearing is a very interesting feeling, and takes some getting used to. Starting off slow would be the best way. It has a tendency to getting a little too hard to handle. But it is certainly a PLUS for this toy!

The vibrations on this toy are all centered right under the Dolphin attachment. They start out very small, soft, and almost tickling. As you slide the control up, they get stronger and stronger. The stronger the vibrations get, the noisier this toy gets. Its not super loud, but its loud enough to be heard from a closed door, if you are just on the other side.

I thought this toy, with all its functions, would go through batteries faster. It doesn't. I've had the same set of batteries in this toy since I first got it a few months ago. I've used this toy at least twice a week.

Since this toy is electronic, with a cord and battery pack, you cannot submerge it in water. The best way to clean it is just with a warm soapy wash cloth. Wipe it down, and make sure you get in all the cracks and crevices. Then do another wipe down with a plain wet washcloth to get all the soap residue off the toy.

Also, given that this toy is Jelly material, I do not suggest storing it right up against any other toys. There is a possibility that it could 'stick' to the other toys, and ruin both.
I suggest wrapping this toy in its own cotton cloth, or in the original package that it comes in.
