Flexible double penetration vibrator by

Boom! Boom! Firepower!

This is a great multi-use double penetration dildo that can be enjoyed by almost anyone whether advanced or a beginner. It even comes with a bullet and all this at such a great price! It is a great investment to make for those looking to experience double penetration in vaginally and/or anally. This is a great toy to have in any collection.
High quality, strong and sturdy, multi-use and double dipping fun.
Can't feel a lot of the vibrations, probe can be hard to insert.

extremely useful review


What is the Flex exactly? Well, it’s a double penetration dildo with so many uses and options. Because of its greatness, it is useful for anyone really from beginners to advanced users. Male or female? Doesn't matter, you can enjoy both the dildo shaft and the bulbed probe vaginally or anally, both holes at once or all in one hole at a time. The possibilities are almost endless.

It does include a bullet that is inserted in the base, this can be hard to insert and remove, applying a very small amount of lube can make this a much easier process. I do not have experience with harnesses or strap-ons, but in my research it looks like this toy can be compatible with both. You would have to verify the harness/o-ring is large enough.

Did I mention there was a bullet? Ladies you can use this on sensitive places on your body while you use the dildo wherever else you see fit! Guys, you can enjoy the bullet inserted into the dildo or stand-alone and also place it on sensitive areas of your body. The base is flared and large enough to be safe for deep anal/vaginal penetration.

Material / Texture

This dildo is made of premium Tantus silicone material making it body safe and hypo-allergenic. There is no latex in this toy and it is phthalates free. The material is very glossy and gives the appearance of a clear coat with a colored underlayer. There are no odors and it is non-porous. It doesn't even really taste like anything. It is realistic looking enough to see that it looks like a dildo/penis, making this far from discreet.

It is very firm to the touch on the main dildo shaft making it difficult to bend. The anal probe is also firm, but because of how thin it is, it is very flexible. There is a slight drag to the surface material but no tackiness or residue.

The bullet is a hard plastic with a shiny chrome coating. It is very smooth feeling with no drag to it, but it is hard to insert inside of the base as it drags along with the silicone.

Design / Shape / Size

There is a lot going on with this toy with all its extensions, bumps and even vibrations. First, the overall length is around 7 1/2". Secondly, the insertable length is around 5 1/4" of the main shaft and around 4 1/4" for the probe. The shaft is long and straight for the most part with a bulbed head that does not have a pronounced ridge. The probe though is very bumpy and gives that extra sensation; not something everyone enjoys.

Average width of the main shaft is around 1 1/2" making it more for intermediate users and the probe is 3/4" more suited for beginners. It doesn't look realistic assuming your comparing it to a penis. When used inside, I find the design generally okay and comfortable including use with the probe solo and using both the probe and shaft at the same time anally. It is harder to travel with simply for the size and bullet that is included.

The bullet measures about 3" long with a width of roughly 1/2" and uses N batteries which are sold here on EdenFantasys. The bullet is very difficult at times to insert and remove from the base inside the hole. Whether the bullet is too wide or the design is flawed, this can be annoying at times. I use lube to aide in insertion and removal of the bullet.

Care and Maintenance

The Flex is easy to clean by many methods such as, warm water and soap, toy cleaner and/or wipes, dishwasher, boiling for 3 minutes or a 10% bleach solution. The bullet is more so recommended with wipes or toy cleaner and it cannot be put into boiling water or the dishwasher. Storing this toy out of direct sunlight is a good idea, also lying on its side and not having it tightly packed is a good suggestion. I use a zip lock bag for mine and keep it away from other toys. If you store it touching other rubber/silicone/jelly toys they can react and get damaged. Flex is big and fairly bulky making it harder to store or travel with. Water and oil-based lubes can be used with the Flex, a test spot is recommended. Some silicone-based lubes can be used with silicone toys, a test spot is also needed and I’d recommend the underside of the base.


The packaging is a larger size plastic container with a clamshell plastic insert. There is a lot of writing on the box, mostly talking about the features of the toy and additional company information. I don't think it's a good storage idea for the toy, it takes up a lot of room and is a hassle removing and putting it back. A lot of plastic is wasted in the Tantus packaging on all their toys in my opinion, not easily recyclable either. The packaging is for all the reasons above, far from discreet.


Using the anal probe and shaft anally is a very fun experience with this toy, the smooth shaft on one side, and bumpy probe on the other create a nice feeling. With the bullet going I can feel a small portion of vibrations, but not much that enhances anything.

    Great review on this! This guy is just a bit too much for me since I do not do the whole anal play thing, but it is certainly interesting! I think switching out the shafts for vaginal use alone looks like fun too, but seems one shaft would always get in the way. An interesting toy for sure though. I enjoyed reading your review.

    Since the vibe doesn't do anything for you, I'd switch it out and use it clitorally while having the rest of it inserted. You must be a size queen, cause I didn't even think to fit both the dildo AND probe in the butt at the same time! You've set a new goal for me....
