Elvie or Willow?

I am heading back to work soon and I’m considering getting a wireless pump so I can keep my supply up. I am a dental hygienist, I see patients every 45 mins so I essentially have no time in my schedule to pump unless it is during my lunch. I’m worried that if I wait until lunch that my supply will drop tremendously. So that’s why I’m thinking that a wireless pump will be the best option for me, so I can at least pump while working.

Does anyone have a willow or elvie? Any recommendations? I’d love to hear all feedback, positive and negative!! Thank you!
