gefühlt die einzigen 27er Flansch, die Verfügbar sind.Keine andere kabellose Pumpe mit 27er Flansch verfügbar.Würde sogar 100 Sterne geben wenn ich könnte.

I would give this item 5 stars if the wait time for restock wasn’t over a month! I bought the S1 Pro breast pump and was super excited until I realized I couldn’t use it for a month! Is there a way to keep pump parts in stock sooner than a month?? Also, my shipping time was adjusted twice to later than expected after the item was in stock.

Been out of stock for months with no date of restock. Eufy is the worst for keeping items in stock. I’m still waiting on a replacement Hub that was placed in February. Highly recommend buy replacement parts so your pump is functioning properly. I also find myself buying replacements parts more often than what their product recommendation is.

I don’t understand how this is an official replacement - it’s impossible to get on my Eufy correctly, so much so that the heat sensor is negated and I can’t use the heat function. The product doesn’t look the same as the original flange, either.

I love the Eufy wearable pumps so much! I was worried about needing a bigger flange size but was excited when I found these. They work just as the original flanges, have the hearing feature which is fantastic, and are easy to clean.

I love the Eufy brand! Their products are reliable and well-designed. While the warming function isn’t very noticeable or doesn’t make much of a difference, it doesn’t take away from the overall quality. I’m still very happy with it and would recommend Eufy for its excellent performance and value.

They came warped and nearly impossible to connect with the collection cups. The heat sensor also looks used and rusty. I don't know why replacement parts seem to be the same quality as Temu but for such an experience pump I expect a LOT better quality when buying replacement parts.Definitely returning.
