Our Verdict
Our Analysis and Test Results
Momcozy specializes in producing breastfeeding and pumping gear designed to support and make life easier.
Efficiency
The Momcozy delivers an average of 0.20 oz of milk per minute, resulting in a total of 3.75 - 4.3 oz during a 20-minute pumping session. However, it wasn't all smooth sailing for this pump.
Our lactating tester didn't enjoy using this pump, experiencing lower output and efficiency. It seemed like she couldn't quite empty her breasts as effectively as she did with competitors. She noted, “I really wanted to like this pump, but it almost felt like it gave up before I did.” The pump struggled to maintain a consistent latch, and sometimes the nipple was pulled without a steady stream of milk flowing into the bottle.
We measured 230 mmHg suction strength at the maximum intensity level, which is shy of the claim of 280 mmHg. While our reading wasn't too far off, it didn't quite match the manufacturer's or more efficient competitors, closer to 270 mmHg.
Comfort
The Momcozy is bulky for something meant to be worn inside a bar. It has a 24 mm flange size. It offers two massage and expression modes, each with five adjustable suction levels. This flexibility lets you customize your pumping sessions, and we imagine some moms will find this is enough.
The entire cup is constructed from soft silicone, which is a nice alternative to rigid plastic. You won't need a specific pumping bra with this pump, but it will likely peek out of the top of your bra. We noticed that synchronization between the pumps can be finicky to achieve. While it's not uncomfortable, it can feel a bit odd when they differ in timing. Our lactating tester stated, “I thought the silicone flange made it comfier than those with harder plastic flanges that were less form-fitting or forgiving.”
Ease of Use
This product would be more impressive if ease of use were solely based on simplicity. However, we experienced issues like leaky cups and seals. Breast shape or size could play a role, so some users may experience something different.
We appreciate that the user manual includes helpful visuals. It's not in-depth, but it is easy to understand and follow. Navigating the user interface is straightforward, with four buttons: massage mode, expression mode, power levels, and suction strength. The pump settings are easy to adjust, and you can cycle through the suction strength levels to select what works best. It lacks a timer, but it automatically shuts off at 20 minutes.
You can't see how much you have pumped while wearing and pumping with the Momcozy. During assembly, it takes a lot of effort to make sure everything is connected securely. If misaligned, the pump can detach from the base or impact milk extraction. We experienced both issues.
Portability
The Momcozy is more portable than some, as it is designed to be worn in your bra and powered by a rechargeable battery. The battery provides up to 1.2 hours of use on a single charge. The pump weighs 0.5 lbs and is tube-free, making transporting it a breeze.
Both pumps will need to be charged, and you need storage bottles for extracted milk, as the cups don't serve this purpose. While it operates quietly, it has a slightly whiny tone, particularly at higher power levels.
Hygiene
This pump has a closed system, ensuring hygiene. Cleaning the components is straightforward; you can do it by hand or with a bottle brush. However, the trickiest part is the assembly, as parts must be aligned. While the task is somewhat tedious, it's not overly challenging with practice.
Should You Buy the Momcozy S9 Wearable Breast Pump?
If you appreciate portability and tube-free pumping, the Momcozy S9 Wearable Breast Pump is an all-in-one contender that's budget-friendly and ready to hit the road. It doesn't require an app, which may be great for those who prefer a less techy product. However, there is a learning curve with the assembly process to minimize the chance of leaking. But, overall, we don't think it is the best wearable.
What Other Breast Pumps Should You Consider?
If you want the best portable option you can wear discreetly, then the Elvie Stride stands out. It features an intuitive app to control the pump remotely, and it logs valuable information. It also has a quiet motor, making it more discreet. While it isn't the most efficient of the pumps, moms who want the freedom of daily living while pumping love this pump and think the trade-off and higher price are worth it. Alternatively, if you need portability but not necessarily hidden pumping, the Baby Buddha allows freedom of movement and a budget-friendly price. While it isn't a hidden collection system as it comes, it can be paired with other cups for more options.
