Smartballs Teneo duo - vaginal balls by Fun Factory - review by DisreputableMog

Do-OH! Smartballs, Smart Choice!

As a beginner, I LOVE, LOVE, LOVE Teneo Smartballs. As I am a beginner though, the mild stimulation that's perfect for me may not cut it for advanced users of Kegel-cizers. As it stands for me now, this is my absolute favorite thing in my toy box. Absolutely get this product, if for no other reason that to see if you want to get something more intense in the same line.
Easy to clean.
Easy to insert/remove.
Variety of colors.
Texture may be too intense for beginners.
May be too mild for advanced users.
Rating by reviewer:
extremely useful review


I had never really heard of pelvic floor muscles or vaginal exercisers before I started cruising Eden's website. It's something I've wanted to investigate since I got on, and I'm so glad I did. Introducing Fun Factory's Teneo Duo Smartballs: These are, as a first time user of Kegel-cizers, great FOR beginners. They're big, but not imposing, and their ergonomic design features help first-timers learn and get comfortable with an important product for gynecological health. Smartballs are the easiest toy I've ever seen to clean - a soap and hot water bath and you're ready to roll. They are quiet/subtle enough to use anywhere, in my opinion.

I will go ahead and throw out a point that was made in the decision-making review I watched before getting this product. These are NOT going to give you results overnight. I can tell after wearing them a few times that, while I enjoy them a lot, I'm going to get the best results with them, for the actual physical health aspect, with continual use over time. While they DO feel good, I don't feel it's probably the best product if you're JUST looking for a toy. If that's the case, try Loa by Close2You.

Material / Texture

Duo is made of velvety silicone, which comes in at a 10 on Eden's Material Safety scale. There is alternating texture that is billed as ribbing, but I don't feel that that's really entirely accurate. I feel like stripping is a better term. Take a look at some of the images to see what I mean. The texture seems to add a little more "oomf" to the sensation, but they can also cause mild discomfort when Duo is used without lube. Once they've been in for a while, this goes away for me, but it's bad enough that I go out of my way to use lube with it now. If I don't have lube, I will usually just pass for the day.

Design / Shape / Size

I love the design of the Teneo Duo Smartballs. They are cute as hell, and they come in a wide variety of colors. They are a little on the large side, which may be intimidating to the beginner, but supposedly bigger is better for beginners. There are two really, really nice features to the Teneo Duo that make it stand out for me, though. First is the retrieval cord. It's definitely on the long side, which can be bad if you are a super-short-shorts girl, or if you are wearing them with a bathing suit. It's also very flexible though, which makes it much, much more comfortable. Second, there's this great little groove at the base of the cord to make it easier to insert. I can see where some models from other manufacturers would be a little slippery, especially when you're using lube. This feature makes the Teneo Duo really easy to push in quickly, comfortably, and discreetly.

On the topic of discretion, these are AWESOME for travel. Except for the smallish diagrams on the sides of the package, I feel like I could leave these on my bathroom counter and never have anyone have a clue what they are. The product itself, I'm confident I could probably hang from my rear view mirror and have no one be the wiser. I'm not planning on trying this theory, but you get the idea. Points in this case for looking inexplicably odd and, as such, unexpectedly subtle.

As far as performance goes, these little suckers are big winners. I was very concerned about over-stimulation when I bought this product. I read about people wearing them all day long, to work and the gym, and thought, "No way. Too distracting. There's no way I could do that." Now...I'm not so sure. They are mildly stimulating, but not enough to drive you to distraction, and easy enough to, maybe not FORGET about, but put on the back burner, if you need to. I like to think about it the same way as I think about wearing a thong, or going commando. It's stimulating because it's so different sensationally, in a passive way, not in an active way.
    • Comfortable
    • Easy to use

Care and Maintenance

This is the easiest thing I own, as far as care goes. Just give it a good wash in soapy water...and maybe use some good toy wipes now and again to keep the really tough cooties away. The box that these come in is small and great for future storage, and once again, subtle, subtle, subtle. Someone will have no idea what they're looking at, unless they really know what they're looking at. I can't say enough about the ease of cleaning and storage of Teneo Duo. It's probably my favorite thing about this product, by far.
    • Easy to clean

Fun Factory really outdid themselves with this packaging. There are instructions included for days, which are very helpful, and a very rudimentary and easy to cover vaginal-insertion diagram on the side. It's a very small, magnet-snap-front box. More detailed information is listed inside a flap on the box, along with a pressed, plastic tray to keep your Duo still and quiet.
    • Discreet looking packaging
    • Good for storage

Follow-up commentary
Still loving my Smartballs. I only have a few follow-up notes to add to my original review.

Fun Factory recommends these not be worn for more than three hours. I find I can comfortably exceed this stipulation, but after about that time, it's less of a kegal workout and more of a stimulatory experience. Which is cool, no complaints there. For my anatomy in particular, these little guys are REALLY fun while sitting upright, and very slightly reclined, so I highly, HIGHLY recommend them for long car rides and, for the gym in general, but especially if you do anything with cycling (spinning, etc).

I mentioned previously that lube is semi-necessary with these bad boys for optimal comfort. I'll also add that insertion and removal are most comfortable when lying down. Insertion while standing or sitting can lead to pinching. Removal, especially if I'm experiencing a lot of stimulation from them, is difficult to get past my muscles to the point of serious pain that lingers for a little while. Lying down to get started or finish up with these guys relaxes your muscles, and also, gravitationaly, clears the way a little.

With a toy like this, that has a fairly mild sensation, it's so, so important to stay in touch with how your body is feeling. If it feels bad in any way, don't bother fiddling to adjust them. Take them out to wash, wait an hour, and try again ONLY if you're feeling better. Remember, if it feels bad, it's contrary to the point, so DON'T DO IT.

Vibe on, Eden.
