These heated massage pads are such an amazing design and helped me so much with engorgement in the first two weeks after my milk came in. I suffered from terrible recurring mastitis and was hospitalised with an abcyss with my first and was determined not to go through that again! The Hakka and the massage pads have been a game changer but I was so disappointed when the massage pads stopped heating up. The heat function is really key. I’m still using them but I’m in and out of the shower all day.
