FYI: This is my first postpartum review so you know this product is highly recommended by me!After getting multiple blisters (and then clogs caused by those blisters) from my electric pumps, I had to resort to using a manual pump. I was using the Medela Harmony for the past three months as my primary pump - up to 8 pumping sessions per day! The suction wasn't great but I was making it work by pumping faster. I wasn't expecting this pump to work as well as the Medela but it is so much better. The suction is far superior, the 30.5 flange size is perfect, and it is so easy to wash. I found mold in the handle of my Medela pump due to the milk flowing up into the handle as the air flows in and out of the pump. This pump prevents that from happening so I don't expect to have any issues with milk drying in the handle area. The only issue now is that I have all these Medela bottles and no extra Lansinoh bottles so I'll need to order more. Lastly, this pump is QUIET! I couldn't talk on the phone and use my Medela pump at the same time since it made noise as the air moved through the pump. The Lansinoh pump is completely silent and you can only hear the milk dripping down.Overall:- Great suction which means less time pumping- Perfect flange size for me- Easy to clean- No milk backflow up towards handle- Absolutely quiet, perfect for multitasking on a phone call or middle of the night pumpingAlthough it isn't ideal to use a manual pump for every session, it helped build my supply up from ~15 ounces per day to ~40 ounces per day over 2 months, thanks to emptying my breasts and hand massage at the same time. Other products I'd recommend with this: Mother Love nipple cream (not lanolin), Lansinoh milk storage bags, and any breast roller for massaging the breast tissue while you pump (more fatty milk and increased flow with massage).
