360 Reusable Breast Milk Containers - 21mm Flange - Holds 4 oz. Per Container - Breastfeeding Essential for The Willow 360 or 3.0 Wearable Breast Pump, Hands-Free Pumping - 2ct

The media could not be loaded. Okay there is a learning curve but once you do learn the turn and flip or whatever they call it, it won’t leak. It only leaks because it’s USER error and not product 9/10. I think it’s brilliant and i think you should get two sets! The only thing i hate is the wait time for air drying. Because it’s enclosed. It take a bit to dry. I typically put it by my window at work and let the sun do it’s thing. If you are smaller than a 24mm, i say go for the 21mm! It’s just right! They say it take 2-4 weeks to adjust but it took me 2 days to adjust and now I’m pumping out my same output with my knock off version of the Willow!

The container is a lifesaver for those that use the Willow pump and cannot afford the bags. I am a nurse and I use the containers throughout my 12 hour shift. I place in the fridge between uses. Though this is no longer recommended by the CDC due to potential for bacterial growth, I have had not problems and this works best for me. The brushes that come with the pump work well to clean the valve in the container, but not really the rest of the container. I use a different brush I purchased separately for that. There are a lot of awkward places to clean. The pumps will stop pumping when the containers reach about 4.3 ounces, but the containers themselves hold about 6.5 when completely full. If you leave the pump latched to your breast (even if pump is off) it is possible to overflow the container (picture included. I've done this several times). Be mindful that there is an airhole in the top of the pump and if you bend completely at the waist, your milk will spill. Milk does not spill if you squat instead of bend.

Update: I ended up calling Willow customer service. They told me to do a vinegar soak for the valve and readings error. 1 part white distilled vinegar to 3 parts hot water. This did alleviate the all full and the clear valve issue. However it consistently gave me incorrect readings and was rarely right on the output. I ended up selling the pump and switching to an Elvie Stride which worked so much better for me._________________I bought these reusable containers because the bags are so expensive, and I go through them so fast which seems wasteful.They were fairly easy to put together and figure out how to use, but one of them quit working after about 5 days. How does a plastic container quit working?1- it started giving crazy wrong readings saying I was pumping 30+oz from one breast when I was getting 1-1.5 oz. I could live with that because there are other ways to measure, but it was constantly (every 2-3 minutes) giving the “all full” notification meaning I’d have to take the pump off and reset it to continue pumping.2- I continued to use it even after the previous issue until it started giving the “clear valve” error and wouldn’t even start. Sometimes I’d be able to reset it and get it to work, but it eventually quit working with the reset.3- After troubleshooting and moving parts around to figure out what was going on, I was able to figure out that it’s the container itself and not any of the other pieces though I still don’t know why it does that.The pumps work fine with the bags by the way, so it’s 100% the container.While this isn’t a review about the pump itself, I’ll still add this to warn others: These pumps are WAY to expensive to be such a hassle, and I honestly wish I’d never bought this brand at all. It seems like they try to nickel and dime you to death (constantly buying new bags or purchasing containers separately from the pump that don’t even work). So buyer beware!!

Been using this pump for under one month as I just had my son on Valentine’s Day went to use it to stimulate production and the left pump isn’t suctioning anymore 😞 I’ve cleaned repositioned it everything and nothing worked even purchased the containers so I didn’t have to use bags and still nada battery life is okay sucks you have to charge them one at a time it should have a charging dock for both at the same time for the price of these I am highly disappointed containers with bags still leaked and it should auto suction milk during the pumping process to avoid filling being the flange should be at the bottom so those that produce less milk don’t have to deal with spillage in the beginning because it is liquid gold for our babies

Ok so I’ve had these a couple months now.Pros:They are reusable.They are easy to assemble.They are lightweight.They don’t always fill up with air like the bags.Cons:They are so hard to clean well.They take forever to dry bc of design.Sometimes they don’t work properly with my app. I will have more than the 0.4 ounces needed to increase suction in expression mode but it’s doesn’t read that I do. I’ll go a whole pumping session thinking I had only pumped 0.2 ounces and take it off to find it to be full.Lastly I just went to pump and found one of my flanges broke where you connect the suction thingy. I am not rough with my pump parts nor do I have any idea when or how this happened. And of course they don’t sell them as a single so to pump both breast together I’d have to purchase again for 50 bucks.So they lasted me 2 months.Hopes this helps other!Over all they have saved me a lot on buying and wasting bags but they are a pain at times.
