The Emigi is a vaginal exerciser that reminds me of the pills from the game Dr. Mario for Nintendo. Inside of the pill shaped body are weighted balls that move around whenever your body moves and cause your PC muscles to contract. I like getting up and doing any little thing that I can when I am wearing these. When sitting down, it is also nice to contract the muscles and have something for them to grasp on to. This helps keep these muscles in good shape and can make sex and orgasms feel better and can help with urine incontinence.

The Emigi is made out of WTP which is non porous, odorless, and phthalates free, it also ranks an 8 on the Eden safety scale. However SinFive's WTP is special because it is antimicrobial which means that it keeps bacteria from growing on the toy. I think this is a great feature because anything that makes a toy safer is a plus in my book!
The Emigi is smooth and pretty firm, although if you squeeze then you can get it to compress a tiny bit. The smoothness is nice because it makes insertion very easy (sometimes I do need a drop of lube though).

The only other vaginal exercisers I have tried are glass ben wa balls. I like the shape and size of the Emigi a lot better and this makes it so that I use it more, which is nice. In regards to shape, it looks like a peanut or a weird shaped pill of some kind. I think this shape works well for my vagina because it is easy for my muscles to hold it inside of me. With ben wa balls, since they are not connected I found that one stayed in place better than the other, but with the Emigi I can keep the whole thing inside with no problem.
The insertable length is about 2 1/2 inches (although there is a retrieval cord that is about 3 inches in length as well) and 1 1/4 inches in diameter. I think this should work well for most users because it is not so long that it will be poking the cervix or hanging partially outside of the vagina. The diameter is also nice because it is small enough for beginners and comfortable to keep inside throughout the day.
Anyone who knows about sex toys or kegel exercise might know what this is, but it might be easier to come up with an excuse ( pet toys if you have a pet) for those who are unfamiliar with this.
These are small and can easily be fit in a purse (if you don't simply want to wear them out) so they work well for travel. I think the balls are some type of metal, so it would not be a good idea to wear them if you might have to go through a metal detector.

My favorite thing about these is how much I can get the balls to move around and how nice it feels when they do move. You will not hear the balls moving, so there is no worry about others looking at you due to any noises coming from your direction.It keeps me aware that there is something inside of me and makes me more likely to do my kegels when I am sitting. It also makes meetings more fun for those like myself who tend to drift off after a while.
I am not sure if it is really a difference or not, but I have had more intense orgasms ever since I started using this regularly. I have had the Emigi since early November or late October. I do notice that sometimes my muscles feel a little tired when I remove the Emigi, so I think this is a good sign of it giving them a good work out.
The Emigi is much better than the glass ben wa balls that I own because with those I could not feel them inside of me.

It is very easy to care for the Emigi. Because it has antimicrobial properties, it doesn't require sterilization. It can simply be washed with antibacterial soap and water.
WTP material can be used with any lubricant, except for oil based. I find that a drop of water based helps this slide into the perfect position where it stays comfortable for a long period of time.
I keep my Emigi stored in the packaging that it came with.

The Emigi comes in the cute little plastic packaging that is shaped sort of like a mini shopping bag with a flap on top that can be used to close it. The package has a picture of the Emigi on the front and the back says that it is a vaginal exerciser, so this isn't discreet.
Inside of the package is also an instruction booklet with some information about the toy in various languages.
I think this package works well for storage and the entire thing can easily fit in a purse. If you want it to not show the info about the toy, then you can take the instructions out and the package will just be clear. Then you have more flexibility in what you tell people the pill-shaped thing in your purse is.

My favorite thing about wearing the Emigi is when I take the bus. Most turns and bumps in the road make the balls inside jiggle around and that makes me happy. Walking up the stairs and up hills is more fun because the balls move a lot. This is good because I find myself taking the stairs more which is good for my entire body!
At the end of the day, I find that my muscles seem a little tired upon removal, so this makes me believe that the Emigi is helping my PC muscles do their job during the day. However, this only happens when I wear them for a 6-7 hour period of time.
