The Purple Monster

The Dynamic Duo has me torn in two directions. I love the vein texture and girth of the larger shaft, and it is great for vaginal use. On the other hand the anal shaft feels too rubbery, and has little or no vibration. If I could break this toy in half... believe me I would. It is inexpensive and can be turned around to be used for vaginal and clitoris stimulation. Overall I believe it has great potential. It depends on the user and how it is being used.
Inexpensive, vein texture, dual action.
Rubbery feel during anal use, very mild vibrations in anal shaft.

useful review


The Dynamic Duo-Dong is rather unappealing to me. I must admit that I was intimidated from the very start. I have developed a love for double penetration, but it usually involves a toy controlled by my partner, and his penis. Dual penetration from a toy was a new adventure for me when I purchased this particular one. I was turned on to buying this product to enhance foreplay with my partner. He loves to see two cocks in me, and I figured this would allow him to enjoy the scenario without him having to penetrate me. I did my studying and the Duo-Dong seemed like the right one to begin with. The size is great and I think the anal vibrator is perfect for users that are just beginning their anal adventure. Although, I was not pleased myself... I think after a few drinks the sensation may change. As long as you can be comfortable with what you are doing this toy could potentially rock your world.

Material / Texture

A major downside of the jelly product is the foul odor that I experience after opening the package. The chemical smell does go away after a cleansing and use, but it is not pleasant at first.

Also, I am a very big fan of jelly vibrators myself, but not for this purpose. I love the feeling of the vibrator in my vagina. I don't think it is suitable for anal use. Jelly material is very rubbery and trust me... rubber does not feel good in your ass!

Design / Shape / Size

The Duo is equipped with a vein covered shaft that does suit me very nicely vaginally. I really am torn in two different directions with this toy. I absolutely love the girth and feel of the vibrator in my vagina, but I not so sure about the anal. It was very uncomfortable at first, but I just may need to get used to the feeling due to not having a lot of experience with this type of toy.

I do have to say that this toy is great for beginners due to the mild vibrations and smaller size of the anal vibrator. If you are like me it will take some time to get used to having something so unrealistic up your ass!

I personally love sex toys, and find myself playing with one every day... but the back door is a whole new world for me. I have not used this toy alone, and actually I think it might be more stimulating if I did. The most uncomfortable aspect of it was that I wasn't in control. My partner tends to get fired up and he likes to get rough, and with toys sometimes that can become very uncomfortable. Also being tense from the very start does not help matters much. My advice would be to try this one out on your own before allowing your partner to use it on you. That way you can get the feel for it and not be so nervous when they use it on you the first time.

The Duo-Dong also has a small string attached to the base that I guess is used to place around you wrist for when it slips away from you, but I do not use this feature.

The Duo is a larger toy, and still can be stored in a larger toy chest. Due to it being a little bigger in size, I tend not to pack it with me on a trip, but it could fit well in a suitcase. I prefer to stick with my mini's on a trip!

Functions / Performance / Controls

You will find the vibrations on a speed dial that has a variety of speeds. They are very slow and can be turned all the way up and still be rather mild. I think this is because you have two shafts rather than one that share the overall power of the vibration. I noticed that in the product description that it states there are vibrations from a bullet in each shaft. However, in the toy I received, there only one bullet in the larger shaft, and so the vibrations are very light and almost nonexistent in the shaft used anally.

Care and Maintenance

Jelly material can't be sterilized like silicone and so no boiling water. Because jelly toys can't be sanitized they should not be shared unless you put a condom over them, which is rather difficult with this particular toy. My advice... keep this one to yourself. You will need to clean this jelly toy with the warm water and toy cleaner. Try not to strong soaps on them because it will ware the material down. When done cleaning, keep in a cool dark place.

Also, as with all jelly products you will only want to use water or silicone based lubes to keep the material in tip top condition.


It has been quite an experience with the Dynamic Duo. Being intimidated possibly ruined my first experience with this toy. I think being relaxed and open to it, could save you an uncomfortable experience. I have found that the jelly is very uncomfortable to use anally, and I will be looking for a better material to use for double penetration. I recommend playing with this the first time by yourself so that you can become aware of all the textures and size. You will decide if you like it or not, and save yourself a really uncomfortable experience with your partner.
Follow-up commentary
Yeah this guy. He just sits in a drawer and very rarely gets used. I don't really like the material. And don't care to use it. I will stick to dp with two toys, because the Dynamic Duo is a mean uncomfortable machine!

    Icky. I'm sorry that the rubber felt awkward during anal. I can see how it'd be awkward. I bet covering it with a condom would help though.
