I have never used that system. I just used the old fashioned breast pads. Now, that I know they have washable that is what I will try next time.
My only cure for leaking was to lean over a warm sink for a short duration - just to get out the excess. It seemed to help when I was home. Because I LOVE to go braless when I'm home. LOL The only embarassing moments would be when I would open the door wet with milk, and it looked like I had been washing dishes in a restaurant with out an apron.
