This toy is meant to be a nipple stimulator to be used on the nipple area of the breast. The idea is to have the cup suck onto the breast area with the nipple in the middle and turn on the vibrators, which are inserted on the outside at the base of the nipple, to stimulate. The little nubs on the inside are then going to vibrate to cause nipple stimulation and excitement. Well, that is what it is supposed to do, but it falls short of that idea.

While you read this review, please keep this in mind when comparing to how it might affect you. I am a DD size and my areola (dark part of your nipple) is roughly about 2 inches in diameter. I state this to give you some idea of the area that these little cup cover and how they work.

First the material: This is made out of TPR, so it is somewhat porous, but if just used on the breast there is not too much chance of sharing diseases. It would still do well to wash and clean before and after each use.

Each one is shaped like a little heart cup (concave) and is really flexible and stretchy. In the middle of the heart shape on the outside is a case for the little bullets. If you wear the heart shape with the point of the heart down, the bullet goes under the nipple area. If you wear it with the point facing up, the bullet goes on top of the nipple area. Right next to the bullet case, the shape has a raised nub area for the nipple. If you look at the last picture on the information page you get a good shot of what this looks like.

Inside the entire concave area of the heart (including the raised nipple area) are little nubs of various sizes. These are supposed to vibrate when the bullet is on to give it stimulation.

I have not found any odor to them and they are nice and soft, so they don't hurt when placed on the breast.

These will collect dust and lint, so keep them in a bag or toy box and clean before and after play.

The design: Cute little heart shapes about 3 inches in full diameter when flattened, but with the concave shape its about 2 inches in diameter when not flat. Like I stated, it looks like a shallow heart cup to fit on your breast, kind of like a suction cup, but there is not much suction to it.

First, it is difficult to get them on quite right unless your nipple is already erect, and even then it is difficult to get it on the nipple, unless your nipple is a perfect fit into a 1/2 inch diameter, 1/2 inch raised area. Even with pushing on it or pressing the nipple area together and releasing it to get suction, there was none on the nipple area itself.

Now the suction cup to the breast had a little more suction to it, especially when it was a bit wet, so you could potentially keep this on your breast while it is buzzing away as it does stick to the breast, but with movement it has a tendency to lose the suction and pop off. The cup does cover the whole areola area of my breast, but for someone much smaller it might cover much more than that. I'm not sure if that would be helpful for suction or a hindrance.

If you manage to get it onto the breast and get the nipple in the nipple area or even somewhat close, then you can just turn the vibrators on with a simple push. It works, and the vibes start. This can be a little stimulating in an over all "Hey, something is touching my breast," but the little nubs that vibrate either do not directly touch the very tip of my nipple, as it cannot get fully into the little nipple area, or they just aren't that stimulating. In addition, the whole suction cup vibes, which to some may be wonderful, but for me it just jiggles my boobs a little. Fun and a nice sensation, but not stimulating.

Bullet Vibrators: Each little bullet vibe is about 1 1/2 inch long and 1/2 inch in diameter. Yes, they are THAT small. The casing is a simple two part snap together piece. When you change the battery, you have to put a fingernail in the little slot and pop the two halves apart (kind of like the snap casing on a phone). Then you have to remove the motor connection, which is the push button part connected to the vibrator (twirling) part by a thin, tiny wire (about 3/4 inch long) that is soldered to the two parts. This has to be removed because the batteries sit under it. The problem for me came when I took the motor connection out because it fell apart. The wire became unattached to the top push button part, and so now it doesn't work. So instead I tried again with the second little vibe, and when I undid the casing for that one, the motor stayed intact, but the plastic casing holding the motor in broke off and it no longer snaps. Out of the two, I have mostly one left, which then ate through the 8 included batteries within minutes.

Batteries: Each little bullet takes 2 GP192 batteries, which are a little over 1/4 of an inch in diameter. They are extremely small and difficult to change. They are also very weak and do not last long (2 times on mine before the batteries ran out, and then one of the bullet vibes broke when I was replacing the batteries).

As far as the actual vibes, they are pretty low power giving a mild buzz that could be felt like a little tickle, but that was all. They were quiet, but then they didn't do much.

As far as waterproof, the cups themselves can go in the water, but the vibes that come with it definitely cannot. In order for this to be a waterproof toy I would suggest getting other bullet/small vibes to use instead (see idea below in experience).

With all the little nubs on this toy, be sure to clean it out with a simple scrub. It's flexible, so you can turn it inside out to make sure to get all the inside clean. Always take out the bullet before cleaning, as the bullet will not be able to have any water contact at all due to its size and design.

As stated it will collect dust and hair and other little particles, so it's best to store it in a little bag or box.

It can be used with silicone or water based lubricants. I have tried to put a little water based cream on the inside, thinking it might make the little nubs inside vibrate better, but not much improvement.

This toy comes in a basic cardboard box (recyclable) with some simple pictures, but mostly easy descriptions on what it is meant for. I do not seem to have instructions (I got rid of that stuff awhile back), but there is not much to them to need instructions.

There is, however, a small little picture with the extra batteries and little bullets that simply show where the batteries go in the bullets, but there is no explanation on how to go about removing the casing and taking out the motor part in order to get to where you put the batteries in.

There are four sets of batteries (2 sets of two for each nipple cup), for a total of eight batteries in a little baggie. That is about the only storage part that is good for keeping. I still have all the parts in my little plastic bag, so if one day I do a video review I can use them.

I will continue to experiment with these to see if there are ways to make them better, so if anyone has ideas for me to try I will be your experimenter and give feedback to the results.

For some experimentation after the little vibes on this broke, I decided to see if other little bullet type vibes worked. The material on the little cups is stretchy, so the casing for where the vibes go can fit other little vibes. The main problem is that most of the ones that fit in diameter are too long for the case (at 1 1/2 inches, so any vibe put into it just sticks out. Not a big deal, just looks kinda funny and adds weight to it, making it a little harder for any suction to hold).

In any case, the following could be used as substitutions to not only replace the vibrators in the toy, but also to make it waterproof for fun in the tub or shower:
