Flange Insert 21mm Compatible with 24mm Flange/Shield of Most Pumps, Insert for Breast Pump Replacement Accessories, 4PCS 21mm

I've only had this pump for a few weeks but so far I love it! It fits together like snapware and doesn't leak as much as the Elvie double pump. The motor part does stick out of your bra so keep that in mind. It also doesn't hook up to Bluetooth or anything like that. The time and vacuum numbers are on the part itself. I personally prefer that, less to cause issues. It also has silicone flanges which is so much more comfortable than my plastic spectra flanges. I actually like this one better than the portable spectra SG. It does great at emptying me out and has minimal parts to wash. I would recommend if you're looking for a wearable pump and don't mind the motors sticking out of your bra. Also, with any portable pump you have to be patient the first few times with leaks and placement.

For any breastfeeding moms out there I HIGHLY recommend this pump. I have used it since my daughter was born and have loved it every step of the way. This pump has been so useful and handy. It has made my pumping journey so smooth and not like a chore. While in the hospital I used the pumping set up that you have to sit and be attached to and it was a hassle and felt like I was stuck and couldn't do anything else. With this pump I am able to continue doing my daily tasks. I can pump anywhere and everywhere, literally. So anyone on a pumping journey trying to find a good pump, this is the one. It is easy to use, easy to clean and affordable.

Compatible with the Momcozy S12 hands-free pump. Solved my painful pumping sessions and improved my milk output!

Just what I needed

Review: I bought the Momcozy S12 Pro wearable breast pump for my wife, and it’s been an excellent choice. She loves how comfortable, discreet, and truly hands-free it is. The 3 modes and 9 suction levels let her adjust it to her needs every day. It’s easy to use, clean, and take anywhere, and the smart display makes the whole process even more convenient. Definitely a product that has made her breastfeeding experience much more comfortable and practical.

Not as great as a normal pump but gets the job done when im at work and cant hook up to a pump

Compré este porque uno de mis accesorios se dañó en el esterilizador de biberones y este es perfecto tal cual

Tried using these in the spectra. It was tough to get them in but they did fit. Also, they ripped up the skin on my nipple. Maybe it works better with oil but too scared to try that now. Maybe they are the wrong size like other reviews say and that’s why it happened. I have no way of measuring. The material just isn’t as soft as it could be. I wouldn’t recommend.
