The Teneo Duo Smartballs are a great concept that I was definitely looking forward to trying. I had my eyes on glass ben-wa balls but was worried that they would be hard to get out and seemed less functional. The Smartballs are two 1-1/2" diameter balls that are each cradled in a silicone pouch and then connected via a small silicone cord. There is also a looped cord that allows for easy removal of the whole entire assembly.

Each of the balls has another smaller ball inside it that rattles around and creates miniature shock waves that are supposed to cause your kegel muscles to contract when the balls are in motion. This all sounds like a great idea and who wouldn't want to get a kegel workout without having to think about it. The idea is that all you have to do is just go about your business and let the Smartballs do all the work. There is even a small depression on the ball attached to the retrieval cord that allows you to place your finger in a more secure position when inserting. Someone was thinking when they put that depression there because inserting round objects that are lubed up is not always the easiest task. Since the pouches and cords are all silicone it's best to use water based lubricants.

I think the balls themselves are plastic and who knows what the inner balls are made of but you can definitely feel them rattle when you shake them in your hand. The Smartballs come in a very well packaged box that give instructions on use and even a small sample of lubricant. It's obvious these balls are built to last and would seem to be the best thing since sliced bread. The other convenient feature is that it's a pretty discreet item that can easily be hidden in your purse if you have to take them out on the fly.

So there I was all excited to try out my new Smatballs, get a good Kegel workout and maybe even a little horny. I unpacked the balls and took the sample lubricant with me and headed to the bathroom. Now inserting 1-1/2" diameter balls is not an everyday occurrence so it took a little coaxing to get them in, but nothing too terrible. I got the first ball in just fine but the second ball didn't want to stay all the way past my inner opening which is where I think it's supposed to be. I could force it in further but it didn't seem to want to stay up there. My guess is that my vaginal canal is just not shaped right or deep enough to keep them where they are supposed to be, which is strange because my husband is pretty big and so is my favorite dildo and those feel great!

I did, however, tough it out and wore them around the house, but it never really felt like anything was happening as far as the Kegels go. After about an hour I decided to take them out because they just didn't seem to fit right and I couldn't feel any contractions anyway. My only guess is that maybe since I was standing up and moving around my cervix was pushing them down too far. Hell, for all I know maybe that's what was supposed to be happening. Anyway, the Smartballs didn't really work out that well for me.
I can see how they could work well if they fit comfortably, but they just didn't work for me.
