single or double breast pump?

depend on branding.. tp kalau mcm real bubee, double breast pump akan kurg suction banding single. bila suction kurang, masa pam pun jd lama. sy try la ubah ia jd single pump. lg kuat n laju.. means, better single than double... tp kene ada milk collector la tuk tadah sebelah lg breast. ni tuk RB je la. pump brand lain sy xpasti. mana la tahu brand lain ada single / double suction mode. hihihi..
