One use only, charger does not work
I just used it one time and the charging cable does not work. Wasn’t even to pump 30 mins, this should come with an extra charger for cases like this, and with how expensive this is….

Wanted to love
Wanted to love these because of how portable they are! I’ve had times where I’ve worn them for 10 minutes and got almost nothing, other times they’ve worked just fine. The flanges are difficult to manipulate in the silicone and similar to some other reviews, it’s occasionally caused a lot of nipple damage, despite the correct flange size. I do love the heat option and again, portability, but my pumpables genie pump is far superior. Also don’t even think about leaning even a bit forward with these bad boys- you will leak!!

Good pump, bad silicone
The suction power is excellent, definitely empties my breasts without issue. HOWEVER, the silicone is so so so annoying. I find it very challenging to line up the squishy pieces to put the pump together for use. I find myself engorged, sweating, and shaking with rage trying to put the pump together. Also, every little piece of dust sticks to the silicone. Also, the texture feels pinchy on my skin. I wish I had gotten hard plastic. Otherwise, the heating feature does feel nice and the settings are very adjustable.

Heated feature stopped working quickly
Heated feature stopped working the second day I started to use the pump. Very disappointed! Also with even gentle mode and low level my nipples hurt after each pump. Would not recommend this product.

Meh.
I was so excited to to get these pumps, after using them I realized that they were completely destroying my nipples. Even the gentle setting was too rough. It made my nipples so raw that I couldn’t even stand facing the shower head and letting water hit them because it hurt so bad. I think that there are better pumps for the amount of money you’ll spend, these simply didn’t work for me.

Motor quit working.
Motor went out after 3 weeks of using it. When I put the pump on and pumped for a 15 min session I would get nothing out. My breast was engorged so it was definitely full. I restarted the pump and would get 3-5 ounces out. This is happening more frequently and I have to restart the pump 2-3 times before it works. Contacted eufy via email because there is no phone number and they have to investigate the situation before sending me a replacement motor. I have noticed a dip in my supply on that side due to lack of being able to pump. Do not recommend this pump for that reason.

Gamechanger
This is such a gamechanger! I get better output than Spectra and it’s so much more convenient to wear and clean. Highly recco!

Even my lactation consultant asked for the link!
This pump is a lifesaver! So comfortable and way less overstimulating than the hospital recommended one that locks me in place with a plug to the wall!

It worked exceptionally well. Enough to keep twin bed for 4 months now
This was for my granddaughter who was expecting twins when I purchased it for her. The boys are now almost 4 months old and she is still using it. It has been excellent for her to be able to feed both babies using the pump. We would recommend it to anyone!

Great wearable option
I seriously loved this pump! My wall pump was a Spectra S1, and I got equal if not better output with my Eufy. Worked great when my baby was in his fussy phase and did not want to be put down. I loved the heating function especially. I would turn it on and let it warm up before putting it on so it would be more comfortable, and it helped with my output and keeping me relaxed. It was pretty powerful and had a couple of options for rhythm which was nice. I will say, the app is slightly delayed…
