Note: you may want to refer to my photos to get an idea of the design, I'll do my best to describe it, but we've established that I'm far from an expert at this.
Deux is two vibrators that "fit" together. Using magnets, these two stick together, looking like a huge egg. Cute concept. When stuck together, Deux is an oval shape. It's totally rounded meaning it won't stand on its own. It'll roll. Not like a ball, but I'm careful when leaving it on my dresser as I have cats and it could get to rolling and hit the floor. The color combination and cute design is fabulous! Down the sides have an "S" when the two are magnetized together. This magnet isn't strong so they come apart easily. It's sort of like a yin-yang type of thing.
My vibrator is concave at one end, so deeply that it doesn't touch my body when put on my crotch. At the other end, there's the protruding, sharp edge. I pretty much despise that darn edge. The male vibrator--also known as mine--is pretty much totally concave. I was kidding about them both being mine, kind of. My partner doesn't love it so I use them both simultaneously if I'm not pressuring him to enjoy the male portion. Toward both vibrator's tips (best to refer to my photos for this one! I imagine my description sounds jacked-up) it's shallow. I'm learning that the tip may be the only way I enjoy "her" portion. Like I said, my portion is too deep to cup my cooter and that's terribly unfortunate. His portion is even deeper! It doesn't touch my body when I try using it, but the shallow "tip" end does. His portion will cup breasts and your bum really nicely though!
SIZE:
Both pieces are longer than I expected them to be, a nice thing. At around 4 1/2" long and 2 3/4" wide, these will fit the majority of both men and women. Both portions cover my entire crotch area, save for the very top of my cooter (I hate the word "mons pubis!")
Not only did the length come as a surprise, the weight did too. Deux is significantly lighter than I expected. It looks heavier than it is. Weighing only a pound and fitting well in a hand, it's fantastic for long periods of use.
SOUND/VOLUME
Deux is not as quiet or as nice as Matryoshka, but it's among one of the most quiet out there. It can be heard in a closed area such as bedroom or vehicle. As with most vibrators, the higher the vibrations, the louder the sounds. All cell phone volumes vary, but this is quieter than most cell's vibrations. It's not any louder than the average cell phone vibration, that's for sure. On the lowest setting, it can hardly be heard (or felt) in the same room as long as some background sound is going. The other settings are about the same volume and cannot be heard through a closed door.
My partner and I did the test, and he could not hear Deux through a closed door. We were charging both Deux portions earlier tonight and he left for a while. When he came back, I had Deux under the covers, on high and he didn't know it. That is until he noticed that only one portion of Deux was on the charger! He said, "Ummm... when I left, I believe there were two sex toys over there. Any chance the other half's up under those covers with ya?" He was not able to hear a peep! When he sat down on the bed with me, the sound was noticeable.
OK and I can't help but share this as well: when my partner and I are driving a somewhat long distance, often I'll get Matryoshka out and hide it under my dress. There is nothing more funny than when he gets in the car, not knowing I'm playing and sticks his ear up to the steering wheel, and says, "SHH!" It never fails. He always thinks the vehicle is making a noise and then looks at me. When we end up on the road for a few minutes before he ever notices, that's when you know it's a quiet one! Deux is louder than Matroshka, but sometimes I can use it in the car without him being able to hear the low setting. This would pass for roommate use.
VIBRATIONS
As I previously mentioned, upon first use of Deux I noticed that the outer shell carries the vibrations better than the inside (where vagina meets inner portion of Deux.) Later I was sure that was true when my partner used it and said the same. In both his and her pieces, the vibrations feel strongest at the end--where it's deep. That's also unfortunate as that area is too deep to really touch my crotch!
I have to admit, when I first turned Deux on, I was so angry. I doubt some of my disappointments in it will ever fade. The vibrations feel similar to that of a twenty-dollar vibrator. They aren't the cheapest and aren't bullet-buzzy, but buzzy is the correct term for these. That's highly disappointing considering the higher end vibrations tend to have nice penetrative vibrations. I've yet to really achieve an orgasm. Surprising since I can get there using almost any vibrator, as long as it isn't a bullet. I think if I can sit down long enough without getting frustrated; I'll make it there, but why spend an hour trying to get there when other clitoral vibrators do it in minutes? While these vibrations aren't exactly heavenly, they are still plenty enough to excite me. Unfortunately, they numb me. A bullet vibrator is so buzzy that it numbs me, making an orgasm near impossible and oral out of the picture due to being numb. Duex numbs me to where I can't feel when my partner performs oral unless we wait a good twenty minutes after use. I really don't like that. However, it isn't as numbing as a bullet. I highly doubt this will please anybody who doesn't have an extremely sensitive clitoris. I am at least moderately sensitive there and I still haven't made it to the end with Deux! This will probably be best used for foreplay.
