Inserts are not necessary for the proper functioning of the breast pump. These inserts are used only to reduce the diameter of the funnels’ tunnel and provide a softer feel around the areola.
Most women’s breasts are not perfectly symmetrical. You may prefer different size funnels or inserts for each breast.
Fitmie inserts must be used in conjunction with, and are not used in place of the Freemie Cups’ funnels.
Different women will have different results with silicone inserts. Some women will find the Freemie Cups’ rigid plastic funnels to be more comfortable. A variety of factors, from the elasticity and shape of your breast tissue and areola to the dryness of your skin to the suction levels you set your pump to will affect which style and size breast funnel will work best for you. Unfortunately, trial and error are required to find the optimal fit and comfort for all breast pumps. And as these are personal use items, returns are not accepted as they cannot be resold.
