SinFive Emigi - vaginal exerciser by SINFIVE - review by Eva Schwaltz

The Little Peanut That Could

This is a neat little vaginal exerciser that holds two balls within it, and they move around when you do. It is really easy to insert, and it has a retrieval cord, making it a breeze to take out as well. It also comes in a variety of fun colors to choose from.
Comfortable fit, Easy to insert and remove, Sturdy retrieval cord
May be too small for some, and ineffective for others

extremely useful review


This is a vaginal exerciser used to strengthen your PC muscles. You can wear it anywhere you want to. Use it while doing your groceries, or attending a lecture. Wear it out on your shopping excursions, or to the movies, or even while going out dancing. No one has to know but you.

In order to get the full effect of this exerciser, it’s best to use it while you are in motion because there are two little balls inside it that move when you do, but no one will hear them. The movement of the balls is supposed to trigger your muscles to contract, which will give you better orgasms in the long run. This is a great tool to use if you have urine incontinence. This isn’t an anal toy, and you may want to look at anal beads instead.

Material / Texture

The Emigi is made of WTP which is a specially formulated thermal plastic often used for children’s toys. The material is non-porous and antimicrobial, making it very body safe. Use a good water based lube to reduce some of the WTP’s drag. You can also use silicone lube if you prefer. Avoid oil based lubricants because they can break down the material, but most oil lubes aren’t good to use vaginally anyways.

The material is nice because you can set the Emigi down without having to worry about it picking up every loose particle it comes into contact with. There are three seams that go around it, but they aren’t that noticeable, and can’t be felt while inserting it or taking it out.

Design / Shape / Size

Others have described this to be a peanut shape, but it is much much larger than a peanut. It is 2 ½ in length, and the retrieval cord is 4” long. I find the retrieval cord to be way too long, so I may cut off ¾” of it and see how that goes. The widest parts of the kegel exerciser are 3 3/4” in circumference, and the narrow part in the middle is 3” in circumference.


The Emigi is an innovative kegel exerciser but it won’t work for everyone. I, for instance, can feel the balls moving around, but they don’t trigger my muscles to tighten. It only weighs 3.4 oz which I find to be too light. If it weighed a bit more, it would offer a better challenge since it is already a nice big size. Despite this, the Emigi is really comfortable to wear. Since I’m already very narrow, I don’t have a problem with it sliding out.

It is really easy to insert and take out. I find a little drop of lubricant really helps, but some people may not even require lube. The cord is a little stretchy, but it shouldn’t break with gentle tugs. It comes in a variety of other colors to suit more tastes. I have the pink and white, but if you don’t like pink, you can also get red, black, fuchsia, or purple.

Care and Maintenance

Regular soap and water should do the trick, but you can also use toy cleaner. Do not boil it or put it in the dishwasher. It is also not a good idea to wear this for longer than 4 hours at a time because you are blocking the vagina's ability to clean itself, and you can get an infection. I usually wear it for about an hour at a time, and that seems to work just fine.


The Emigi comes nicely packaged in a little plastic case that is great for storage, but you can store it wherever is convenient for you. There is a paper insert that gives you care instructions, and further information about the product. It also features some of the company’s other products that you may be interested in.
Follow-up commentary
This is really not an effective kegel exerciser for me. I've worn it out and about, but the balls jiggling inside aren't that noticeable. I think this would be better suited for those who are new to kegels because they would get a lot more use out of them.
