I did not like them. I could not feel anything and felt that they did not do anything. They did not help strengthen my vaginal muscles, nor were they "pleasurable" as they are told to be. If I had not put them in myself, then I would have never thought they were there. I tried walking, jogging, squats, etc. and I could not feel anything nor did they work.
