I really like Fun Factory toys. I feel that they make things out of a high quality material and they have quite a few toys in their product line. I purchased the Smartballs for a few different reasons: 1) While researching, I found that these had great reviews, and 2) I am a mother of 3 and felt that these would be good for helping to tighten things up.


When I first received these, I really liked how pretty they were :) They have a little bit of weight to them and you can feel smaller balls inside of the Smartballs that kind of jingle inside the two Smartballs. Smartballs are meant to be inserted into your vagina and held there using your PC muscles. This is a good way to strengthen your PC muscles. These have some size, so it's not likely that they are going to fall all the way out of your vagina, but if your PC muscles aren't in good shape, you will feel some slippage. Another intended purpose for these is for stimulation. While they are inserted, and you move about (walking, etc), the smaller balls that are inside the Smartballs move around and stimulate and massage your vaginal walls.


The first time that I tried them, insertion was somewhat uncomfortable. I used some lube for insertion and this helped quite a bit, but it also made it a little harder for the Smartballs to stay put. I was a little too ambitious and decided to where them while shopping. I wouldn't recommend this. I ended up having them slip out a little bit, which caused me to walk funny until I could get to a restroom to remove them. Obviously, this was an embarrassing situation. Instead, I should have tried them out at home for a while first.


When I tried them at home, I just wore them as I went about my daily chores. I found them to be very stimulating - part of it was feeling the massage action of the movement of the balls while I moved around and part of it was knowing that I was using these without anybody else knowing what was going on.


I noticed that after wearing these for a period of time during the day that I was very turned on and that when I had sex later, my vagina actually felt tighter. Obviously, it wasn't permanent tightening from one day of use, but I think that it was partly the stimulation and partly just a temporary tightening from having used my vaginal muscles for an extended period during the day.


I really only have one complaint about these. The string that extends out for removal is made of plastic and if the Smartballs slip out even a little bit, it is very irritating. If you are in a private place, you can obviously reinsert it and remedy the problem, but if you aren't in a place where you can do that, it can become quite uncomfortable.
