The food grade vinyl and elastomer, all mechanical dual vibrators, are Japanese products. The silicone ones are from Germany and Japan. They offer a combination of clitoral and penetrative stimulation at the same time. That’s why we call them dual vibes! Their shafts rotate to create stroking on the vaginal walls, while the external vibe flicks the clit. Both elements are separately controlled so you can customize the action to what works for you. The range of movement in the shaft is key. If you were to use these toys in a thrusting manner you couldn’t maintain contact with the clitoral vibrator. It is also important to note that the full length of the shaft must be inserted to have clitoral contact with the vibrator. But for the silicone ones, note that shafts made of food grade vinyl or elastomer have a nice softness but are porous and difficult to clean (elastomer less so but... ), so a toy cleaner (see vibe accessories) is highly recommended. No sharing, either. Silicone cleaning requires just soap and water, and the material is non-porous.
All mechanical things ultimately break down. High-end vibes last longer but they all fail eventually (you will find it difficult, if not impossible, to have your vibe repaired). The rotating shaft’s mechanics operate under a lot of stress, when you consider the clenching of the vaginal muscles. We must point out that the all mechanical duals are not designed for a full on interactive experience. They should not be “ridden,” they should not be manually rotated, and they should not be “clenched” upon with all the user’s might. If you impede the shaft’s rotation it will either struggle to move on or stop entirely. If you want all the bells and whistles without interaction, by all means go for an all mechanical dual. The pro side of an all in one is that there is no added creativity needed to get from A to B. However, if you want a toy that has partner play potential, whose motor is interchangeable and whose shaft is interchangeable then a build it yourself is the answer. Which means you should move on to our build it yourself dual alternatives. If you’re sticking with considering an all mechanical rotating dual vibe, we are showing you high quality dual Japanese and German made vibes and those who use ’em love ’em! We caution you not to be fooled by manufacturers producing products that look deceptively similar and are named to trick you. There are a whole slew of cheap copies out there but not in here. As a point of interest for those wondering, “What’s with the little animals?” Japan has a law against the export of goods depicting human genitalia. The Germans just seem to have a real sense of fun.
