I use them. They're fine. Don't know which brands I have by now as they were bought 6 years ago when ds1 was due. They've since been used by my sister for 2 babies and are now back with me, still going strong!
So when you use reusables how often do you change them, because whenever I feed, the opposite side pours out and I don't fancy having a wet pad on my nip all day. So I'd just be changing them all the time and would need about 20 to get me through day and night. Are the extra absorbent or something?
I must say I gave up on reusuable breastpads (and I am a hardcore cloth-nappier). I had EmmaJane ones and I leaked so much that all my tops ended up with breastpad-sized damp circles on after an hour or so .
