Great gift for new moms

Got this for a new mom who works in the medical field and doesn’t have easy access to fridges. She loves it!
Also lovely customer service experience - quick, easy, and nice representatives

Perfect for work!

I love having 2 inner chambers for easy pumping at work! It’s lessened the number of dishes I have to do and really like that each one can hold up to 12 ounces. I had an issue with my package arriving damaged and customer service was excellent in replacing!!


This was a replacement and the customer service to get this was 10000/10! They were so helpful and so quick to get this to me. I greatly appreciate their help!


I bought this as a gift for my daughter. She absolutely loves it! Keeps her breast milk cold all day which gives her a peace of mind.
