Review on Maymom Pump Valve & MyFit 27Mm Shield Compatible With Lansinoh Breast Pump Signature Pro/Smartpump/Manual Breast Pump. Replace Lansinoh Pump Valve. Not Original Lansinoh Pump Part (27Mm Shield+Valve) by Gary Perry

For my second baby, I was able to work with a great lactation consultant who sized my nipples and I discovered I was even smaller than I thought at 17 and 15 mm. This product was great to add to a manual lansinoh breast pump that I had. I didn't even bother with the flanges it came with since they were way too big. I use my manual pump during car rides amd it works well with this flange. I am able to fully empty my breasts and get a great output of sometimes 6 Oz or more for both breasts. It's helped me feed my baby for the past 3 months and have a freeze stash. Thankful for this company to make this product since lansinoh doesn't offer their own smaller flanges in this size.
