I love love love the Haakaa brand and have many of their products. I was after a more durable nipple shield and these correctors as my nipples have since become flat… I thought it was worth the investment despite the price. Unfortunately, I was very disappointed and would not recommend this product or the nipple shields made by Haakaa. After wearing the correctors they worked for about 2 mins then went flat again. I believe this product is a bit of a gimmick and not helpful at all.
Thank you for your review. We can assure you the Haakaa Inverted Nipple Correctors are not a gimmick. However, they do need to be worn consistently for a period of time - they are not a once-off fix. The Nipple Corrector work by pulling the nipple into a small cup. This stimulates the nipple and makes it protrude. When used over time, they can help loosen the nipple tissue. This can help your nipples remain erect for longer periods of time. Hope these helps :)
