Great pump for every day!
I really like this pump so far. I was hesitant to order because it's a new-ish product and there aren't heaps of reviews, but I'm glad I did. I've personally found the output similar to my old Spectra S2 and it's a game changer to not be tied to an outlet while pumping. I've find it secure enough that I can do most things (include holding a squirmy 6-month old) with no leaks or need to re-adjust.
The only thing that's a bit frustrating is that it's hard to initially confirm if you're getting any milk since the battery sits on top of the milk compartment - this is easy enough to solve by either waiting a few minutes and checking the compartment, or simply using a mirror. Also, I find their app very basic and a bit clunky so generally don't use it - the pumps themselves are really straightforward to operate so no issue there.
