I was nervous about ordering my breast pump through Edgepark based on the reviews found on Yelp, but it was a great experience for me! My OB sent them my breast pump approval directly (I have an HMO and they required it), and after confirming with the office, I just filled out the online form, selected the pump I wanted, and received it within the 7-10 days like they said I would.
Overall, great experience, with a quick delivery! However, I didn't have to interact with anyone in customer service. I would definitely recommend having your OB send the prescription/order in directly, if you can have it done.
