The Dynamic Duo Vibrating X-10 stimulates the entire inside of the vagina. It can be used on the clit, but it doesn't work as well as a lot of other vibrators that I've tried. It is, however, the best internally stimulating vibrator that I've tried. I think that this vibrator is better suited for toy users that are a little bit more experienced because of the unique shape and the intense vibrations. One of the great features about this toy is that it has a removable suction cup feature that allows you to stick it to just about any flat surface that you can imagine. The suction cup has really strong suction too, so no worries about it coming loose during playtime.

The Dynamic Duo is made of PVC, which is a type of plastic. The texture is smooth and slick. The material gives off a slight odor and has a slight taste to it. Neither the taste nor the smell are unpleasant though, and if you're not specifically looking for them you probably won't even notice. One of the benefits of PVC is that it is water resistant, which is great for those of us who love bath and shower play.

The Dynamic Duo is 8" long with and insertable length of 6 3/4". The toy has a long tip and a long end with two ball shaped pieces in between. These pieces stimulate the lips and the entrance of the vagina when you insert the vibrator, and the feeling is wonderful. Also, the way that it's shaped in addition to the material allow the vibrator to be really flexible without hurting the toy. Since there is a suction cup attachment, this flexibility allows the user to experiment with a lot of different positions without discomfort. As far as the shape of the toy being discreet... well, it just plain isn't. I wouldn't suggest leaving it out or traveling with it.

The Dynamic Duo's performance was astounding. It was much better than I could have hoped. The vibrations are very strong and can be felt throughout the entire vibrator. The button that controls the vibrations is located at the very bottom of the Dynamic Duo. Press the button once to turn it on, then press it again to turn it off. When you press it a third time it turns back on but on a higher setting. Although the toy is advertised as having three settings I only detect two: one low (but not too low), and one orgasmically high. The best thing about the toy is that even though the vibrations are very high it is virtually silent.

To clean the Dynamic Duo you can either wash it with antibacterial soap and water or with toy cleaner. One of the few drawbacks is that this toy is a pain in the butt to clean because of its shape. You have to really get into all of the grooves to make sure that its really clean. The only lubes that should be used with this toy are silicone and water-based lubes.

My favorite use of this toy so far was when my boyfriend put the suction cup on his chest. Then I rode on the vibrator while he played with my clit with his tongue. It was amazing! Like I said, suction cups = endless possibilities
