The top layer wicks away "moisture" so you don't get that "gooshy" feeling. The adhesive on the bottom seems better than the Ultra pads. It rips free without tearing, something that started being a problem with the Ultra pads. I like the tapered shape and the way the pad stores "moisture".
I have been using the Diva Cup for almost a decade, and the thought of going back to tampons and pads is horrifying. The Diva Cup has saved me hundreds of dollars, reduced the severity of my cramps, and nearly eliminated leaks. I can use it without worrying during the most vigorous exercising.
