The nipple n adaptors leak. The warmer is ok. Instruction says to use approximately 2 cups to fill but mine only takes 1 cup. The only thing i like is the convinience to pump directly into the bag.
Overall it’s a great product, I love the idea. The bottle is a little bulky but I like the bag idea. The nipple is a little hard to clean and gets dirty pretty quickly but with the cleaning tools that come with the whole kit I imagine that won’t be an issue. Whatever minor annoyances with the product I still intend to use it
