The SinFive Emigi is a small vaginal exerciser that is about 3.4 ounces in weight and comes in many color combinations. The vaginal exerciser itself is about two and a half inches long with about a three and a half inch retrieval. The EF colors are accurate, and the real product size widget is accurate as well.

The SinFive Emigi packaging is really nice. It comes in a small, plastic-like box that easily reseals for easy packaging as well as includes a picture of the product and is very classy. The packaging just shows the products and doesn't show any half-naked women or anything. The packaging display actually can be removed from the product, and it has instructions on the inside as well as it explains the features of the Emigi.

The Emigi has a very smooth and soft texture to it. It is not plushy in the slightest, but it is made from a hard, firm material that is slightly matte. Because of the matte texture of the material, I would highly recommend using a lot of lubricant to lube this up before attempting to use it. The material will absorb lubrication easily, so it may take a couple applications during a long-term use. For four hours, I took it out twice for reapplication of lubricant both times I tried this toy out.

Attached to the Emigi is a retrieval string. The retrieval strings seems very firmly attached. I've given it quite a few hard yanks, and it's never come out. I even sat and attempted to pull it out, but it does not come out of the Emigi. However, a concern is that it may tear if you pull TOO hard as it is a rubber-type substance. You can try pulling the string before you insert it to see how far it is until the breaking point, but as long as you aren't bearing down when you try to remove it, I imagine you'll have absolutely no issues with the removal string.

The weight the Emigi is pretty average. It's not too heavy, and it's not too light. I'd say that most people would be able to easily retain it early on, but it might be harder to keep this in as time goes on due to the heavier weight which is where the exercising comes in. The Emigi is slightly larger than one ball of most of the two-ball systems, and it does stay in really nicely. It does feel a bit longer than most other vaginal exercisers, though, so that's something that I had to get used to. It also isn't nearly as flexible as the two-ball systems because it's just one piece. There is a seam between the two different colors, but I couldn't feel this seem during use.

I can't say that I've noticed a difference with my vaginal muscles, but I don't use it nearly as often enough for this to happen. Even though I've used heavier balls before, this one definitely starts to feel heavy after awhile of using it, so it can work great for exercise. The balls inside the Emigi rotate quite a bit, and as long as you're doing a minimum amount of movement, you can feel them rotate. I wouldn't say that the sensation is arousing in itself, but it does keep your attention focused on the area which could definitely be arousing.

The Emigi balls are made from WTP which is a thermoplastic that is microbacterial resistant. The material has a built-in ability to prevent the growth of microorganisms on the surface of the toy. The packaging recommends cleaning the Emigi before and after every use with warm water and mild soap. It should NOT be boiled or put in the dishwasher, and it's compatible with all lubes except oil-based ones. For storage, I recommend keeping it in the original packaging, but it won't hurt it to be stored outside of packaging.

Overall, I liked the Emigi. It's not going to work for every body type, and I'm not sure about the long-term effects of vaginal strengthening, but it is extremely easy to insert, easy to remove, and can definitely give you a work-out. Plus, it's an attractive little toy, and it comes in fun color choices for whatever your preference.
