I've been modifying my cup to suit my suction needs, and it has helped a LOT. At first, I couldn't break the suction for anything. I tried cutting the holes a small bit bigger, and it only helped in the fact that it wouldn't suction back together when I was taking it out. I cut them bigger again, and it made popping it out a little easier. I cut two more holes in it, up by the others, and found that it made it even easier, to the point that I'm pretty sure I've done it correctly this time. So, for anyone who has trouble with the intense suction of the Diva, if you are careful and are willing to buy small sharp objects, then you should be able to correct your troubles through trial-and-error.
All in all, I am VERY happy with this cup, and if its OK with my gyno, I will definitely keep it and use it while I have the IUD, if capacity allows.
