I finally tried these today, and I have to say I like them more than the Teneo Uno. You could feel the pressure and the movement which in turn caused some VERY nice feelings down below. Even after pulling them out, the muscles down there are a good deal sore and tight feeling. It was like they are still constricting like they did when I had the duo in. I got these because after having two kids I felt I wasn't as tight as I used to be before said children. But I think if I use these on a regular basis I might be able to get back to my pre-pregnancy tightness. Definitely going to buy another set of these in Pink because you can't have too many.

The vibrations are wonderful. I think these would be wonderful to wear while doing cardio, Yoga, or pilates. I like the fact I can pop these into the top rack of my dishwasher to sterilize them for a more thorough weekly cleaning.

My only issue is that it is a bit difficult (resistance) to put in but, adding a few drops of K-Y Liquid to the top on the first ball being inserted solves that issue. By the time I pull my beads out they are so lubed up by my own natural lubrication, that they just pop out with ease. The sensation that is created by removing the beads is very pleasurable as well.

They can be used as a toy with BDSM. My husband and I have been doing light BDSM & Japanese rope bondage for the past 5 to 6 years. For anyone who has read the 50 Shades series, you know what I am talking about. Teasing during this type of play is easily done with Teneo Duo. The pressure from rope bondage across the vaginal opening or, having your partner slowly pull out one ball and leave the second one in there just to give you a wonderful fullness and stretching sensation right at the vaginal opening is a great way to try them with this type of kink.

As I said earlier, I like these better than the Uno because I was actually able to feel them. The weight of both balls made every thing better, and feeling the vibrations helped my muscles clench up every time I made any type of significant movement.

I would definitely recommend these to my friends because most of them have kids, and I know that their sexual health is extremely important to them.
