Question about haakaa pump

Des • Have two lovely girls 👧🏻👧🏻 one 😇 👦 👧🏼 and now we are expecting our second boy God is good 🤰👣👶🙏🎁😍

So this is my forth pregnancy and I have heard a lot about the haakaa manual pump. I have all ready received the lansinoh pump which i will use when baby is asleep or just in between feeding but I will like to give it a try to this pump as I am feeding her I saw a video and it seems so good to be able to collect the milk we leak from one breast as we are feeding in the other. It can collect up to 4 ounces almost 😳. That is so amazing I leaked so much with my other babies I don’t want to loose any of that gold liquid this time.

Has anyone use this product before ? Tips, ideas, and recommendations accepted.

Thanks

I am also going to buy this little milk collectors for when I am out and about have
