Amazing passive pump!
This is a great in-bra alternative to a haakaa! I get slightly lower output than I do with the haakaa, but this also doesn’t suction quite as firmly as the haakaa does. With my first, I would just wear a nursing pad on the other side when I was out of the house and needed to feed him, but this allows me to catch all the milk that would have otherwise been soaked up by a nursing pad. The design allows it to have surprisingly strong suction while still being comfortable to wear. I highly recommend this, and it worked so well that I ended up buying a second one!

Great Haakaa alternative!
This is great! I liked the idea of the Haakaa but my baby would always kick it off when nursing on the other side. I liked that this sits in your bra, no risk of it being kicked off! It has great suction. Definitely will be using while nursing!

Not Great
Good concept, but unrealistic. This falls off with the slightest touch/bump.

Haakaa alternative to catch letdown
This item is easier to clean than other similar products, but is really better as an alternate to the haakaa. As someone who does not leak despite having a strong let down, I felt it was a little misleading as a product, and was overall rather useless for me.

It’s pretty good
I’m a breastfeeding momma and I would definitely recommend this product to collect lose milk. Instead of it going to waste, it can go to a bottle. It holds us to 3 ounces. The only bad part of it is that it’s bulky, but I got over it

Easy to use
LOVE IT! I have used a Hakka and disliked the fact that baby would always knock it off or my toddler would take it off when I was breastfeeding two at one time and he would drink it lol. So this time I’ve decided I need something like this! Got 3 oz just walking around cleaning up a little bit! Got approved for a Zomme pump through my insurance so this will be helpful making me still able to be mobile while my new baby naps and my 4 & 2 yr old run around! Still need to be able to put milk away at the end of the day just in case!

Absolutely Recommend
One of my favorite milk collectors. Super durable and convenient to use, its flexibility saves me a lot of frustration!

Buy it!
Love this. It’s comfortable to wear, I have been able to get about an ounce collected with every feeding (great for triple feeders like myself). I wish there was an easier way to empty it, I have just found turning it upside down and using the lip in a curve to pour it out has worked.

Great product that allows me to catch letdown rather than wasting it in a nursing pad! I find it cumbersome at times to feed my daughter on one side while using a pump on the other (especially when using cross body feeding position or my nursing pillow) and really only wanted to collect any extra milk. I thought I would give this a try and am happy I did. It’s comfortable, easy to use, doesn’t fall off while my daughter is squirming and collects a good amount of milk that would have otherwise gone to waste. It’s also great to be able to collect that milk in a passive way that won’t increase/potentially cause more oversupply than I want, plus you’ll only need to wash one item rather than all my pump parts!
