### ⭐⭐⭐⭐⭐ Works amazing!
*by S***A on August 7, 2025*

Love them! I've been using them in my hands free pump and my hands pump as well and I feel like I'm actually getting empty. My little man is 3weeks old and a great eater but I'm an over supplier and this is helping get the rest of what he's not able to get out!
