Flexible double penetration vibrator

Double Whammy!

The Flex by Tantus is sure to please with its minimalistic dildo design and bulged anal penetrator. It's easy to clean and sterilize and it can be used in the bath, shower or in a harness. The versatility of this toy is attractive but the button placement on the bullet makes it difficult to ride the dildo while it's vibrating.
Material, Included bullet with battery, Sterilizable, Double penetrating, Harness compatible.

extremely useful review


The Flex by Tantus is a double penetration dildo that's meant to be used by women but men could use this too if they just bend the anal penetrator out of the way or away from the dildo section of the toy while using it. This dildo would be great for g-spotting if you don't require a lot of pressure to stimulate your g-spot.

This dildo would be better suited for those who are already used to penetration but would like to try stepping it up by trying out double penetration. The size of the dildo is about average and the anal penetrator piece is about the size of a small pinky finger so it would be great for those who can't handle a lot of stretching.

The Flex comes with a separate bullet vibrator that can be inserted in the base of the toy to add to the overall experience but it isn't necessary to enjoy the toy. The bullet and the dildo are both waterproof so using this in the bathtub or shower is a possibility and warming or cooling the silicone will add some fun temperature play to it.

Using the Flex by yourself is a great experience but it can be used for foreplay with a partner as well. It can also be used in a strap-on harness on a female partner since there is a wide base on the bottom of the dildo. It is not really recommended to try and use this in a strap-on harness on a male partner only because it would be a pain to try and keep one part of the dildo out of the way while you use the other part to penetrate.

Material / Texture

The Flex is made from 100% ultra-premium platinum silicone which gives it a 10 out of 10 rating on the Eden materials safety scale. This means that the dildo is hypo-allergenic, non-porous, latex- and phthalates-free and food-grade material. There aren't any odors to the toy upon opening the packaging and the material is smooth but grabby with the exception of the anal penetrator which is bulged. Being grabby means the silicone will pick up all kinds of lint and hair so washing before and after each use is required. The color chosen is the Midnight Purple but it also comes in a lighter shade of pearlescent purple called Purple Haze.

Silicone is somewhat grabby so using lubricant with it is necessary. Only use water-based lube with your silicone toys unless you've already spot tested them. To spot test, just put a bit of silicone lubricant on the base of the toy and wait to see what happens with it. If it becomes gummy or overly sticky it isn't 100% silicone, but I've never had that problem with any of Tantus' silicone toys.

The bullet is made from a shiny, silver plastic and has a rubbery push button that turns it on and off. It also has a waterproofing ring around where the cap screws on to help keep out water. The Tantus logo is stamped onto one side of the bullet and its tip comes to a point.

Design / Shape / Size

The Flex is a classic shaped dildo, straight shaft and vague looking head, with an anal protuberance that is thinner and bulged for added stimulation. The dildo is 7 1/2" long in total length with 5 1/4" of the bigger dildo piece being insertable and 4 1/4" of the anal protuberance being insertable. The dildo diameter is 1 1/2" or 4 3/4" in circumference and the anal protuberance measures about 3/4" in diameter or 2 1/4" in circumference. The entire dildo doesn't weigh too much, maybe about a pound at the most.

The silver bullet that comes with the Flex is about 3" in length and 5/8" in diameter. It can be inserted into the base of the dildo for added stimulation or it can be used separately as a clitoral stimulator while you use the dildo so you get the perfect trifecta of pleasure.

Care and Maintenance

Cleaning the Flex is simple enough, just wash it with warm water and antibacterial soap or toy cleaner. Same goes for the bullet since it's waterproof. You can also wipe them both down with toy wipes or isopropyl alcohol. To sterilize the dildo, without the bullet inserted, you can boil it for a few minutes or toss it in the dishwasher without detergent. You can also wipe it down with a 10% bleach solution but be sure to rinse it thoroughly to avoid getting harsh chemicals in sensitive body areas.

Storing the Flex can be a little tricky because of its size unless you keep the box it came in. Even that isn't great long term storage so finding some kind of pouch or bag for it will be necessary at some point because the box is quite flimsy. Once you have it stored in a pouch or bag you can keep it with your other toys wherever you happen to store them.


The Flex came packaged in the typical clear and red, see through plastic Tantus box. The toy is clearly visible through the front of the box and it gives a few tidbits of information about the toy. The sides of the box list out some more information about the toy in several different languages and the back of it is somewhat opaque and lists information about Tantus' silicone. The dildo and bullet are sandwiched in between a clear plastic insert and the bullet was already pre-loaded with it's own N battery.

There weren't any instruction booklets or warranty sheets included in the packaging but it's easy to figure out how to use this toy. The packaging is made of flimsy plastic and would make terrible long term storage. It is also not discreet at all and should be wrapped if gifting to someone else and recycled when empty.

Personal comments

The intensity of the bullet is probably about 3 vrooms which is moderate but dampened a little further by the silicone and the noise level is about 2 bees. It will most likely be heard through blankets but not through a closed door, especially if there are other background noises like TV or music.


My preference for using this toy is riding it and having the bullet vibrate on my clitoris at the same time. The vibrations do carry well through the silicone but it isn't strong enough to really get me off. Using some lubricant with this toy is necessary but it doesn't take much to get it slippery and feeling good.

I have to say that it's not easy for me to use double penetration toys when they're larger than this but the Flex was small enough to work out fine for me without being painful.
