I got this product on recommendation of my gynecologist, as a back-up method. She also showed me how to use it. I used the sponge properly and not only did it get stuck, but after following all the directions in the information sheet about how to remove it, it ripped apart as I was trying to get it out. My boyfriend had no luck either, and the entire ordeal was awful for both of us. I ended up going to an emergency clinic (because we were out of the country) to have it removed. When it came out it was torn in several places. The gynocologist who removed it for me (with some difficulty) said she's seen them get stuck before but never tear. I then developed an infection because not all of the pieces came out. One came out over a 2 weeks later when I got my period.I had wished this would be a great back-up method or primary method some day but I'll never try it again.
