How do you feel about a used breast pump from someone you don’t know?

Update! I just quit my job this week so I won’t have insurance when the baby is born. However, my husband is native so he gets free healthcare through the tribe. I get full prenatal care through them and they take care of me for the 6 weeks after birth too. My child will have the same tribal benefits my husband has when it comes to healthcare. So there won’t be an insurance company to give me one for free. I can afford to buy a new one though, which is what I’ll do. I just thought maybe I had come across a fabulous deal.
