It didn't work. Also, it doesn't suction well. Even when the breast is full - hardened from milk, it doesn't easily extract milk. It is tiring and it is preferable to press the breast to extract milk, resulting in tired hands and a sore breast.
Also, the pump doesn't do a good job.
Also, the price-to-product ratio is disproportionate.

It didn't work for me, and it also doesn't collect the thin milk that runs from the other breast while breastfeeding the baby. It only collects the fatty milk. To collect the fatty milk, you either need to use a breast pump or let the baby breastfeed, not this one in any case!!!! So, for the purpose I bought it for, which is storing milk supply, it doesn't work because it doesn't collect the nutritious milk!

"It suctions to the chest and is suitable for use while breastfeeding from the other breast, even with the known leakage. It has collected up to 50ml of milk! It requires caution, of course, because if not applied correctly, it can be painful. It has a storage container for breast milk with a lid, as well as a bottle nipple. It has been very convenient for me! There is also a more economical option on the market, but I believe the price difference is due to the additional things provided by Dr. Brown's (case, bottle)."
