The Green Dolphin is a cute little toy great for beginners. I think I say that more often than I should, but this time it's very true.

The toy is made out of a soft non-porous, phthalates-free and latex-free silicone. It's got a smooth rubbery texture and an adorable dolphin face. It takes a single AA battery, has a twist dial controller on the bottom, and a nice hand-friendly shape.

The fact that it only takes one battery is both a blessing (don't have to search for a matching pair when you need one!) and a curse (a little weak, to say the least).
The bright neon green color is a little shocking in a sex toy; not something you see every day, but it makes it oddly attractive and lovable.

For clitoral stimulation this thing isn't exactly a rocket. The one battery means that the sensations are really low. Luckily the dolphins nose provides a perfect tip to concentrate the vibrations, and with the right amount of concentration, its good for those soothing, warm orgasms that feel so wonderful every now and then. It's also very very quiet, which is great.

Insertion may be a little difficult because of the rubbery texture. Make sure to lube it up with a water-based silicone really well before trying to ride it, otherwise you might have to twist it like a screw to get it inside. Otherwise, it's a good size for the job, decently sleek, and the curve of the tip sends the light vibrations where they need to go.

For couples play this is a little too big to fit between two people, and a little too weak to really be noticed amongst the other sensations you'd hopefully be feeling. It's a great idea for exploring each others bodies with the gentle vibrations, and makes a decent foreplay toy.

I don't know whose idea it was to make a vibrator that takes only a single AA battery, but it was a silly thing to do. For me the sensations are pleasant, but couldn't get me to climax. It got me close many times though, which is definitely saying something.
I think this toy would make a little more sense if it were rechargeable or something else that made it eco-friendly, giving a wonderful double-meaning to it's name.
