So I got to hold one on person the other day and play with it, I was pretty impressed. The nipple is odd and doesnt actually have a tip..its a huge hole lol. The way it works is similar in a way to the breastflow in that it doesn pour. I held it upside down and shook the mess out of it, but it only allows a small flow instead of a huge one for harder/faster sucking. My guy refuses bottles so I have no idea how it works.
Yes and he hated it!
Mind you, my son refuses bottles as well.
The nipple seems too long so he would gag whenever it was in his mouth. The hard and strangely shaped nipple doesn't mimic a breast at all. And disassembling and reassembling the 2 part nipple for each cleaning was extremely tedious.
I wouldn't recommend it.
