Have not yet tried the bags or the pump parts. I’m a first time mom and my milk supply has been very very minimal. On the other hand, did use the bottle warmer. It’s a 10/10 for me! Honestly worth the buy! I only got this because I had a 50% off coupon. I suggest you wait to see how good your supply is before buying the whole pack!
This is such a great deal. Warmer is so easy to use and quick. The bags are perfect since I have less dishes to do, and I love that they're recyclable. Has everything I needed to start my pumping journey.
