How can efficient pumping be ensured?
1. Please use the nipple measuring card to determine the appropriate size and choose a suitable breast shield or flange(15/17/19/21/24mm).
2. Fully charge the pump motor. Confirm that the breast shield and airbag are properly installed and sealed.
How to ensure the normal suction of the breast pump?
1. Ensure the accessories are installed correctly without any gaps, and cover the milk pouring port.
2. The breast pump needs to fit tightly against the chest.
3. Keep the battery fully charged and select the appropriate gear.
How to clean/sterilize breast pump accessories?
The only four parts that can be cleaned/sterilized are the milk collector, valve, diaphragm, and flange. They can be cleaned and sterilized by warm water, ultraviolet light, or steam (time ≤ 3 mins, temperature ≤ 100 ℃)
Do I need a special bra for pumping?
Suggest bra style: Full coverage bra/stretch fabric/with nursing buckle/wireless bra/sports bra. A bra with support and fit can achieve the best results, and the package comes with bra strap adjustment buckles.

Good
I personally enjoy this pump. It’s my new go to for a wearable. It’s got strong suction, long battery life and easy to use. I would recommend this pump.

Amazing affordable pumps!
I was rather skeptical about this breast pump as first but it definitely surprised me! I ordered this pump as a back up for my other 2 pumps so I could switch out when the others need a wash. Now I find myself reaching for it the most out of my Elvie stride and eufy heated pumps. I get great output especially as someone that has an oversupply the suction is great! It’s listed to hold 6 ounces but I have had it hold roughly 10 ounces on each side. The product comes with extra parts flange covers so you can just pop them in the fridge once done and then Ben comes with a carrying bag. The motor its self is compact and can be carried around your neck. The noise is a little louder than my others but doesn’t really bother me or my baby when I have them on. Overall this is a great product and works very well for the price!! Would highly recommend these pumps!!

Wrong color and terrible product
I didn’t get the color I ordered and the pump isn’t evenly suctioning, meaning only one side is pumping. Do not recommend buying this product. I like the idea of the pump being portable but it sucks.

Fantastic!! 😀❤️❤️
This electric breast pump works very well. It’s comfortable, easy to use, and saves me a lot of time. The suction is good and it’s not too loud. Very helpful for breastfeeding moms.

Good for the price
I use this when I’m on the go. Works well when fully charged but as it dies it dosnt empty like I would like. Easy to clean and put back together.

Great motor that works with Medela wearables
Pros:- Motor is strong- When first starting, it defaults to the vibration (triangle) mode so it doesn’t hurt. It remembers the last setting you had each mode on, as well.- The connector port for the motor is surrounded by silicone, so you can use other connectors – I was able to use my Medela pump in style wearables with their normal tubing with no issue.- The double flange on the cup is very secure and comfortable, and the silicone flange has a large rim on the bottom of the cup so it can’t pop off.- The end connector for the cups comes off somewhat easily (it won’t fall off, it’s just not glued), so you can use the cups with a pump like the Spectra if you want- I have never used mine until it dies, I usually charge it after about 3 usages (50%), so the battery life is good.- The motor is small/discreet, and has a little clip on it. I’ve clipped it in on my bra or stuck it in my pocket to walk around doing stuff while I pump.Cons:- I feel like the cup doesn’t get much suction, and I don’t know why exactly. But this is a really personal thing (could work just fine for someone else) and as stated, it’s a REALLY comfortable wearable. I tried the cups with another pump and can confirm it’s the cup, not the motor causing the suction issue.- The power button is a little finicky, like it’s slightly off from the symbol where it should be. But it works.Overall this is a great portable pump. Well worth the $50ish I got it for.

I really wanted to like this pump
For some background, im an exclusive pumper who pumps about 8 times a day. I used to be an overproducer then my supply plummeted but now im up to making just enough. My primary pump is a spectra s1. If this pump works for you, it does empty me like my spectra does. Im giving this 3 stars because it just didn’t work for me however it can work for others. It’s not terrible.Pros:-affordable-minimal parts to clean and comparable to other wearable cups-very compact motor-comes with a clip and lanyard-love that it comes with flange covers and a jawstring bag.-i appreciate that it comes with a variety of flange sizes-really good vacuum (be careful its strong) and typical cycle speeds-love the mixed mode. Its about 5 short pulls followed by 5 long pulls. I like this compared to the short pulls and one long pull that’s seen in other pumps.- not touch screen so you dont have to worry about accidentally touching somethingCons:-cups are really bulky-it wasn’t very comfortable for me. Maybe its the vacuum or the cups-short battery life. I do the full 30 minutes to completely empty (which is quite long compared to other pumps I’ve used) and I had to charge after every 2 pumps-a bit loud for my liking-when it’s clipped onto you the screen is hard to read. Its upside down so I would have to detach it to read it. (Not a big deal though)This is really affordable and I do recommend that you try it for the price
