Edenfantasys' offers us Ultra 'O', a Cal Exotics product. It's a vibrating bullet that is a waterproof mini massager that is wireless and powerful for it's size. It's also very quiet. It's designed for both clitoral and shallow g-spot stimulation. And it's one of the smallest vibrators you will find.

Although part of Ultra 'O' marketing is geared toward it being a g-spotter, there are many uses for it for both ladies and guys. Tease any erogenous area for exciting stimulation. Use on your body yourself or pleasure your partner. Use solo or as a couple - take your pick. It's a great vibrator for beginners, even for more advanced users as well. And it's waterproof so take it with you into your shower or bath, with or without your lover.

'O' is the first vibrator I have discovered that is created for travel. The mini massager can easily fit into a pocket or even a makeup bag. Since it is so whisper quiet, and I mean it's quiet, you can use it if you are sharing a room with someone else. In fact, you can even use it while your partner is sleeping soundly next to you. They will never know, that is, unless you tell them later.

Ultra 'O' is made of ABS. ABS is a hard durable plastic. ABS is phthalates free, non toxic, hygienic, hypoallergenic, latex free and non porous. It is one of the safest adult toy materials. And it has no odor right out of the package.

'O' has a straight tube design with 2 added features. It is bulged about in the center of its length. The bulge is smooth. Then there are 4 nubs on the inside of the upper curve for added stimulation. The vibrator is slick, smooth, and has has a shiny matte look. As I move it down my arm, it glides so smoothly. It has a smooth cool surface.

Ultra 'O' is about the size of a lipstick tube in length and circumference. The top 1/3 is a gentle curve with nubs along the inside of the curve. It is bulged in the center of the length of it. The bulge is large, porportionately, on one side. On the opposite side there is a slightly smaller bulge. About the lower 1/4 of the massager is the battery cap. There is a control twist dial at the bottom of the cap. Then at the bottom of the controller is a retrieval cord attached.

I find I use the lower 1/3 of the massager to hold on to. The battery cap just isn't long enough for me - my hands are of average size. I'm not sure why there is a retrieval cord since Ultra 'O' is designed to be a shallow g-spot vibrator. Who knows, maybe it works to vaginally insert, i.e., use as an egg. Wait a moment, I'm going right now to research that.

Ok, I'm back. Ultra 'O' does work as an egg. It's not the shape of one, but it does fully insert. And I can feel the vibrations vaginally out to my outter Labia. I don't feel the vibrations as strong internally as externally. So, I think it's better to use it vaginally for shallow g-spots as well as external stimulation. I don't have a shallow g-spot, myself. Here are the dimensions:

Length: 3 1/4"
Length Insertable: 2" - 2 1/2"
Length of Battery Cap: 3/4"
Circumference Tip: 1"
Circumference at Bulges: 2"

During my online research for Ultra 'O' I came across information stating it has multiple speeds. Well, that's not the case with my 'O'. It has one steady speed. And that speed is powerful for the size of the massager. Also, there is no on/off control, although, I've read there is. In fact, once I've inserted the batteries, just the contact touching the batteries starts the vibrations. So, I really don't see the purpose of the twist dial controller.

I'm not sure if I have a defective vibrator here. Since it does vibrate, I'm assuming it is not defective as I write this review.

The vibrations are easily felt the whole length of the little vibrator. Oh, and a nice feature of Ultra 'O' is that it comes with its own batteries which are the round watch batteries. 'O' uses only 3 batteries that comes with it, but Cal Exotics provides 3 extra batteries. It's quite uncommon for a vibrator to come with batteries.

Care for Ultra 'O' involves clean up and storing. Clean up is easy since it is waterproof. Just wash with warm soapy water or use toy cleaner. Be sure to air dry before storing. Because it is made of ABS plastic, there's no need to be concerned about it having any material breakdown. However, since other types of materials may bleed color or melt on it, it's just simpler for me to store it separately. I use a baggie or pouch and sometimes the original packaging if it's really nice and of good quality to store all my toys. Be sure to remove the batteries before storing to prolong their life.
