Purchased in 2020. It has been washed, disinfected, and stored carefully. Operation has been confirmed. All accessories are included, so you can start using it immediately upon arrival. Buying new is expensive, but I struggled with it. However, when my child was in the NICU, the double pump helped me save time with visits and expressing milk while sleep-deprived. I patiently increased my milk supply with the breast pump, and it took three months until discharge, but I was able to breastfeed after leaving the hospital.
