BabyShown Rumble Tuff Go Cups- Hands Free Collection Cups. Sizes 24mm Breastshield and 21mm Insert. Compatible with Medela Breast Pumps and Spectra Breast Pumps. 8 oz Storage Capacity Easy Cleaning

I have a spectra S1 and it is such a good pump but I loved the convenience of my momcozy wearable pump. My momcozy never emptied me though and I only got about half the milk I usually do with my spectra. I ordered this to use with my spectra and it has been a game changer!!! Seriously love it, easy to clean, is comfortable to wear, and works perfect with my spectra s1. 10/10 recommend!

I absolutely love these cups. I use them usually only 2 times a day because I have more than 1 pump and collection bottles. I use these with 19mm inserts and a Spectra s1. I get really good output with these, and as a bonus they're easy to clean with only 4 parts. All of my pump parts get washed in a portable dishwasher with a basic detergent. The reason I am giving a 3 star review is because it seems as though a duck bill valve is already going bad. I had to stop a pump session because the part came completely out, and everything started gurgling. This wouldn't have been a big deal had milk not come spilling out of the inlet because of the pressure release of opening the outlet cover. Overall I love the cups, I just wish parts weren't going bad after only a week or so of use.

I was previously using a wearable pump to pump on my commute to work, which I felt wasn’t adequately emptying me and, if even slightly misaligned, wouldn’t pump milk at all. I saw these cups and decided to use them with my spectra s9 for a different portable option. I got so much more milk and was very pleased. The cups aren’t super discreet but you can remain clothed and decent (unlike regular flanges) so I found it fine for commuting. I took off one star because I feel like I need to replace the valves pretty quickly and they are specific non mainstream parts, which may be harder to track down.

Wow! What a great addition to my breast milk pumping gear. I was not a fan of using original breast pump attachments that come with spectra S1 pump, and these cups have changed my breast milk pumping experience to the best. It’s so easy to insert these into a sturdy nursing bra and attach the tubes connecting pump and cups. I’m still able to move around the house while holding my spectra pump (S1 rechargeable model in blue color) in one hand. The original attachment and bra that I have to use with them are extremely uncomfortable for me. The suction power is very good. They have a large capacity of milk to be collected, which will last me for my entire breastfeeding and pumping time with my baby. The cups are very easy to assemble and to clean. I love the pink-lilac color accents of the caps, very cute. One thing I’d like to warn you about. When you disassemble the cups for washing don’t pull by the pink rubber hole cover on top of the cups, it will eventually start ripping off. I find it best to disassemble the cups for washing while my hands are dry. Otherwise if the cups are wet it’s very slippery and hard to grip them to pull apart.I’m extremely satisfied with these breast pump cups and highly recommend them to breastfeeding and pumping moms out there.

I ordered these thinking it was the whole system it's not, just the cups, luckily I am able to use them with my other system I have and it's always nice to have extra cups

These BabyShown Rumble Tuff Go Cups are well made and easy to use. They are compatible with my Medela breast pumps. Very useful when I pump. Worth trying!

Got these to be more handsfree with my Spectra pump and they fit without issue and actually work surprisingly well. My 3 stars are due to the fact that I had issues with them leaking and the parts are hard to find replacements for since it uses much thinner tubing than the Spectra does. If they stayed sealed better and used the same tubing, these would be perfect!

Enter the realm of hands-free convenience – where multitasking moms meet their match with this innovative pumping accessory. As an engineer and a mother, I can't help but admire the design and functionality. These collection cups integrate effortlessly with my existing Medela and Spectra pumps, offering the luxury of mobility which is a godsend for an on-the-go lifestyle. The clever inclusion of different shield sizes ensures a comfortable and personalized fit.I was pleasantly surprised by the closed system design, giving me peace of mind about hygiene, and the ease of assembly means less time fiddling with parts and more time for me. The storage capacity is generous, making sure I'm ready for little one’s next meal. Pumping can now happen virtually anywhere, without the usual tether to a stationary device. Being able to insert the tubing at any angle is a small detail with a big impact, providing the flexibility I need.On the technical side, there's a notable efficiency in milk collection, although I'll admit it's not quite on par with being directly connected to the pump – but the trade-off for freedom is worth it. Cleaning is also straightforward, a relief for any parent who values their precious spare minutes. Sure, they could use a nip and tuck to match the suction level of traditional setups, but they stand strong as a commendable companion for nursing parents. And with components that are BPA free, I have one less worry while providing for my little one.
