This was only gifted to me, pero I used Wisemom Pomona. It's double electric and you can get a breast pumping bra (available in lazada/shopee) din so you can get some work done while pumping :) meron din silang iba ibang sizes ng flanges depende sa size mo. Oh and once you start pala, start with the highest level that you can tolerate. If masakit sa boobs, adjust the level lang. May instructions naman kasama. https://babymama.ph/products-page/wisemom-pomona-rechargeable-double-electric-breast-pump/#
