Purchasing used breast pump?

Brittany • Mother of 2 boys( 6/11/08 and 7/4/17) DH had vasectomy, IVF fresh cycle #1 BFP November 2016, Baby born Independence Day 2017, can't wait for baby #3 in a few years! 👶🏽💙❤️💙❤️

Do you think it’s okay to get a used breast pump? I would only be using the motor as this is all I need and I purchase brand new parts for my pump. I just wanted an extra motor for work. What’s your take on this? Is it okay?
