Electric Breast Pump

Moms, ano po marerefer nyong best electric breast pump for exclusive pumping? I'm a working mom po kasi and my nipples are too small talaga. Sa 1st baby ko failed ang breastfeeding journey namin due to my lack of knowledge na rin sa breastfeeding. Ngayon po, balak ko talagang karirin na ang breastfeeding kahit man lang exclusive pumping. So ano po masasuggest nyo na pang-malakasan at matagalan na gamitan na double electric breast pump? Thanks sa sasagot.
