I found mommy express to be a very easy site to use and navigate. customer service reached out to me within 24 hours of me submitting my information online. They were really respectful helped me finish filling out what needed to be filled out and gave me a timeframe and I received notification after they finished what they needed to and got all the stuff approved that my breast pump would be here within one to three days and I wanna say it took me less than 48 hours to receive my breast. If I had the option to use mommy express again I would but being that I think I just had my last baby. I don’t think I will need an upgrade on my pump, but I would recommend mommy express to any new mother or mom that has already had a baby and need to breast pump.
