Has anyone used the willow pump?

I have seen a few posts about it on here but it’s mainly from people who have never used it giving opinions so im wondering if anyone had any actual experience with it??

Im a nursing student and i really dont have time to go sit in my car for 20-30m several times a day. Id like a pump that i can use without much interruption in my day and thats the big promise with this pump, just wondering if it lives up to it? The second edition comes out this month and baby isnt due until July so i will probably get that one but from what i have read, only a few things have changed.

TIA!
