Joy-the product is a clear soft plastic device, round with an outside shape similar to a soft plastic breast shell. The inside has a little plastic "button" that put pressure on the nipple. The device cannot collect milk, tho it does come with a flannel pad to catch drips. The idea, of course, is to maintain enough pressure on the nipple to stop leaking. My concern is that the constant pressure MIGHT cause other problems, such as plugged ducts, or.....??? I was hoping someone else had had more experience with them than me and could offer input :) Denise [log in to unmask]
