The Deep Diver Dolphin is a cock ring and sleeve rolled into one. This item is used by slipping over the penis and works by allowing enough blood flow into the penis, but decreases blood flow out. Due to the nature of this product, it is not advised to wear this product for extended amounts of time. Unlike a lot of clit stimulators, the nose of the dolphin reaches high enough to work quite well while still getting deep penetration.

The Deep Diver Dolphin is made of TPE, which is a rubber polymer and has a material safety rating of 6. TPE is a soft material with a lot of grip to it. It is very stretchy.

There are 2 textures in the dolphin that stand out and create extra sensations. On the inside are 4 rows about half an inch apart which, for me, didn't do much, but helps keep it in place. The second is on the outside of the sleeve and is a raised spiral ribbing that increases her pleasure.

The design of the Diving Dolphin works great as a clit stimulator with removable vibrator, while still being nice to look at. It also hits all the right spots that are deep. The sleeve fits snugly over the penis and doesn't slide around like a few other sleeves I have tried. The sleeve is comfortable to wear.

You may need a little bit of lube to get this on. I find that a quick lick from my girlfriend or a small amount of lube does the trick.

The length of the sleeve is just under four inches. As is the height of the dolphin from tip to tail. The tail end of the dolphin extends 3/4 of an inch beyond the sleeve. The tip of the dolphin's nose also extends 3/4 of an inch beyond the sleeve while the top of the head is about two inches beyond.

The dolphin contains four small metal balls around the tip of the shaft. While these are intended to provide added texture, neither myself, nor my girlfriend noticed them.
