The suction is good when it actually works. I've had 2 of these pumps so far. The first one constantly leaked and the second one cracked on both the flanges in the same week. I have to order new parts... again.

Do not purchase this version!
If I could give it zero stars I would. I ordered this pump and when I finally went to use it, it stopped working within 5 days of use. It would no longer charger or turn on. I was sent a replacement and the same thing happened the device stopped working mechanically and would no longer turn on. I have completed lost faith in the brand itself. It really has interrupted my milk production for my baby and was such a huge inconvenience being that it happened suddenly and twice !

Disappointed
I’m almost 12 weeks postpartum and one of my pumps has stopped working. I am combination feeding and do not have time to pump each breast individually, so this is a huge issue. The convenience of this product is what drew me in, but unfortunately the longevity/quality isn’t there.

Better options available
It does the job. The best part about it is the app. However, the suction is not great and it is easy to spill the milk when pouring it into a bag due to the opening of the milk collector cups. There are much better options on the market. Even the MomMed one I got off of Amazon for less than $100 is better :/ I am eagerly waiting for the new year when I can get a different one through my insurance.

Do not buy!
Please save yourself the money and do not buy these pumps. Within a month of using these, my motor went out. It took FOREVER to work with their customer service and they finally sent me a replacement. I've had another part break three times since then and now they will no longer replace it. Now my motor is going out again in the other pump and it has caused my supply to decrease. Same thing has happened to my friend who also uses these. Her motor has gone out and is having to be replaced. For…

These pumps broke after THREE WEEKS OF USE. I reached out to Momcozy for replacements and they sent me used pumps with dried milk on the parts. Absolutely disgusting and a huge health hazard.

Hands free breast pump-Gift for daughter
It worked good for about a week or so and one of the pumps stopped working. She called to get a replacement and Momcozy told her they would send her a replacement but as of now still nothing. It’s been about a week and a half now. Still waiting.

The freedom!!! I wasn’t too sure if it would have the same strength my pump at home has but it definitely does and surpassed my expectations. 10 out of 10
