Hands-Free Collection Cups Compatible with Spectra S1 S2 S9, Replace Breast Pump Kits Compatible with Spectra Breast Pumps, 27mm Flange + 17/19/21/24mm Inserts

This works perfectly with my Spectra S1. The suction is great and having the extra flange inserts was very helpful. I had the same output that I normally get. It is easy to put together, take apart and clean (parts are small so could be easy to loose). This is a great option to help make a wall pump more mobile. It fit under my nursing bra well.

Love these for my spectra

These work great if you are stationary, sitting upright. I bought these so I could try and multi-task while pumping for my twins. Minor issues with leakage and not getting good suction if I try to move at all.

I hardly ever leave reviews but this was bad. Within minutes of putting them on my left side was leaking or backfiring back onto my nipple areola area, i could see my milk pooling arond flange and insert. Does not fit securely on breat, I do have bigger Breast so this may be a reason. Only got 1oz when my output for morning after feeding my baby is 2-4oz. Over not impressed with how they feel on kept pushing and insuring they were snug because im active in morning with other kids and just kept feeling like they were going to pop off my Breast. Poor sucks so bad I had to take apart to get remainder of Milk out.

Obsessed doesn’t even cover it. This was the best purchase I’ve made for my postpartum BFing experience. The cups are super high quality, come with a ton of extras like duckbills, flanges, and o-rings. They fit well in a regular bra, sports bra, or nursing bra so it’s very versatile. For my next baby, I will be buying this again.

Sometimes these work great and sometimes I don’t get any output from one side. They often leak into my bra and when I pull them out milk will spill out. They are a good affordable option and do make pumping hand free when you need, I still use them just wish they were more consistent!

I'm really glad I went with these cups as I was looking at a few options. I have a Spectra pump (s2) these connect perfectly and collect just as much milk. Easy to assemble and take apart for cleaning. I can wear my nursing tanks and bras, no need for specific pumping bras with the holes, which I love. Comes with additional parts which is also a huge plus. I can hold and tend to my baby much easier while pumping. I can appreciate that they come with different size flange inserts and sizer! Super important for a comfortable pump. I would reccomend this product!

For me they leak. Good luck trying to get them into a bra if you're big chested. Just get a hand me down mom cozy
