Breast pump

So I finally got the email from Aeroflow telling me that I was approved for a breast pump through my insurance and there’s a buuuunch of different ones I can choose from.

I am a FTM and can’t decide which one to choose.

I would love to hear your experiences with what you used to help me determine which one to get.

Also, I don’t know if this matters or not but I have flat nipples. I’ve heard pumping/breastfeeding can help that but I just thought I would include that because it was something I am worried about.

TIA!
