Some flaws

I feel oblige to share my experience because I had lots of doubts before buying it because it is not cheap.
I have flat nipples so bf my first child was very challenging and couldn't make it. This time I am expecting twins so I am determined to bf not matter what so I gave niplette a go. I have been using it for almost two weeks 8hrs a day and I start to see some positive changes. My nipples stick out more and more time, and when I am not using it I wear a breast shield to avoid my bra and clothing put pressure over them and make them flat again.
Be aware the entire process is not easy and in my case it caused pain not in my nipples but in my areolas where the edge of the cups stand. I think that if the cups or at least this part of them would be made of a soft material (eg silicon) the problem would be fixed. Using it at night is not easy as well. Unless you use a well fitted bra the cups will come off. These are the reasons why I am giving it three stars.
I believe niplette will work but it needs time and consistency when using and in my case some pain.
