I bought one and had it in my suitcase at the hospital, and found it really handy when my milk first came in and my breasts were really full, it made it easier for me trying to juggle bub, attachment, huge breasts, pillows etc.

Once home though I really haven't used it, moreso because the size of my breasts calmed down as my milk settled and I've got my own set up of pillows on the couch and more confident with different positioning/attachment etc.

The purchasing was snap quick though, really on the ball and I had it within a couple of days. HTH
