The Cal Exotics Sensual Swirls vibrator is a multi-speed vibrator made up of TPR, with a plastic cap that serves as a dial for controlling the vibrations. The TPR doesn't really give off much of a smell, and, as far as I can tell, has no taste except for a very minimal rubbery flavor. Use a water-based lube with it, it can be cleaned using your regular methods(toy wipes, toy cleaner, etc), but be careful not to get the cap/battery end wet, as it is not waterproof or water-resistant. Also, since this is made of TPR, if you are planning on sharing, or using this for anal play, be sure to use a condom for safety.

Yes, the Sensual Swirls can be used anally, as the base has a large bulge to prevent it from slipping in all the way, though the bulge is almost the same size as the one at the "head" of the toy, so you might still want to be careful. The bulge at the head feels great pressing against your P-spot, as well as the G-spot, so it's a pretty versatile toy. I find that the length (about 7"/18cm insertable) is good for both doors, any longer or shorter might take away from its versatility.

The "head" swirl is about 4.6"/11cm around the widest part. There is some give to it, but it is still firm enough to press against your P/G-spot, and the bullet is located 1/2"/1cm from the base of the swirl, so you get a good amount of vibration at this end.

The vibrations carry fairly well throughout the whole toy, so they can even be felt at the end swirl, giving you some extra sensation against your clit/labia/perineum/etc. The dial base turns the vibe on and off and controls speed, but I found the lowest and highest settings were pretty similar. The vibrations are pretty quiet; I couldn't hear them in the next room with the door open. I put it in the bathroom (which echoes) and closed the door, but I couldn't hear it even with my head right next to the door, so it's pretty discreet. No worries for those with nosy roomies!

The "shaft" of the Sensual Swirls vibrator starting under the "head" swirl, is about 4"/10cm in circumference, while closer to the base it is 4.5"/12cm, which is a noticeable progression, but just slightly so. The crease running lengthwise down the shaft feels nice but it also not terribly noticeable. This is a very smooth toy without texture, and slides really nicely (lubed) while thrusting; I also used a bullet vibe on my clit for added sensation.

It's interesting to note that the two swirls/bulges don't line up together. What I mean by that is that they are slightly off-kilter, and don't line up exactly. I'm not sure why this is, I can't think of any advantage to this feature, but it doesn't detract from its use either. Just something different, I guess.

While this toy does provide G/P-spot stimulation, it didn't work quite as well as I was hoping it would for that purpose. Nonetheless, the stimulation was nice and I do enjoy this toy quite a bit.

The toy's performance hasn't changed any; it's still a vibrator I enjoy using occasionally, but hasn't become a favorite either.
