I really, really like the concept of this product. I found first insertion to be a little difficult and I couldn't 'snap' it into place behind my pelvic bone as other reviews instructed. The second time (after my first emptying) it did and I thought 'oh sweet, now I know it's in right'. Well, the next morning turns out it was in too good and I had to have a doc take it out w/ forceps in the ER. There was no way I was getting that thing out...I couldn't grip anything.
