Breast pump suggestions

Hello pumping princesses,

I have been exclusively pumping for about two months now and i am unsure if i am using a quality pump.

I have the avent duo hospital grade pump and it seems to work fine to me, but when i told a lactation consultant last week i was using this pump she told me the pump was not a quality one. I dont know any other exclusive pumpers and was wondering if any of you ladies had any thoughts!

Any and all opnions welcome! :)
