Aww first time mommy, congrats! Personally I'd be careful with secondhand breast pumps kasi it's hard to know kung fully sanitized na talaga and if all the parts are in good condition, a few of us tried it and ended up having leakage or suction issues, super frustrating. Better to check kung may rent-to-own options sa hospitals or clinics near you, or wait for sale seasons sa Lazada/Shopee, kasi the peace of mind is really worth it, honestly!
