Hakkaa breastmilk catcher/pump

So, I’ve seen and heard a lot about this product lately and I’m curious.

I have a 1 year old who was EBF for the first 6 months and now I’m 20 weeks pregnant. When I breastfed my daughter I did end up pumping quite a bit starting out and then later on when I didn’t have to pump I noticed that I had a lot of milk waste due to leaking.

I plan to breast feed again so that’s is why I’m curious. I hated feeling like I had a vacuum on my chest all the time with my first. Lol

So my question is... is the Hakkaa really all that it’s cracked up to be on social media? Have you used it? What are your thoughts? Pros and cons?
