Whether you have a job, run errands, or want hands-free time at home, these pumps make life easier.

But how do you choose when there are such great options? Let’s break it down.

Design and Portability

Momcozy M5

The Momcozy M5 is sleek, condensed, and super lightweight. With its simple interface and minimalist design, it is easy to assemble, use, and clean. Better yet, due to its petite design, it can fit in your bag without taking up much space — a big deal for on-the-go moms.

Willow Go

Compared to the M5, the Willow Go has a more modern and a little bulkier design. It fits easily into most nursing bras and enables discreet pumping. Its durable construction gives it a nice sense of heft, and some moms might consider it a tad less portable thanks to its size.

Winner: The Momcozy M5 wins the lightweight portability category for moms.

Powerful Suction and Adjustable Settings

Momcozy M5

With powerful suction of up to 280mmHg, M5 has 9 suction levels and two pumping modes (Stimulation and Expression). This flexibility gives moms the ability to tailor their sessions to their own comfort and productivity.

Willow Go

Willow Go also has great suction power, maxing out at 280 mmHg. It also has two modes (Stimulation and Expression) and several suction levels, making its performance on par with the M5. Moms looking for consistent, hospital-grade suction will be satisfied with either pump.

Winner: Tie—both pumps have remarkable suction power and are customizable.

Noise Level

Momcozy M5

Perhaps the best feature of the M5 is the virtually silent motor. At less than 45 decibels, the pump operates quietly enough for pumping sessions at the office, meetings, or next to a sleeping baby.

Willow Go

Willow Go is a bit louder than the M5, but it is still whisper quiet and falls comfortably within the territory of low-decibel performance. It isn’t as stealthy as the M5, but it’s quiet enough most of the time.

Winner: For moms who want a near-silent operation, Momcozy M5 wins by a mile.

Milk Collection and Capacity

Momcozy M5

The M5 uses 5-ounce (150 mL) cups for milk collection. This capacity is acceptable for most moms, but if you have a heavy output, it may need to be emptied even more frequently.

Willow Go

Willow Go has the exact same size pump and pump size: 5-ounce (150 mL) milk collection containers. The difference is it is compatible with spill-proof milk bags, so it is easier to store and transport milk.

Winner: For its added versatility with milk bags, it’s the Willow Go.

Comfort

Momcozy M5

Some may find silicone shields more comfortable, like this one, which offers soft silicone shields only. It also has customizable suction levels to help moms strike that important balance between efficiency and comfort.

Willow Go

Willow Go also uses medical-grade silicone in its flanges and shields, so the comfort is on par with the M5. Some mothers find that Willow Go fits them better, thanks to its more ergonomic shape.

Winner: Willow Go wins by a small margin on overall comfort.

Battery Life

Momcozy M5

The rechargeable battery of the M5 lasts up to 3 sessions on a full charge — very good battery life for busy mothers. USB-C charging also makes it more easy to use.

Willow Go

Likewise, the Willow Go offers good battery life, giving you around three to four sessions on each charge. Its charging dock is simple to use, though it may seem less accessible than USB-C.

Winner: Momcozy M5 for USB-C charging convenience

Price and Value

Momcozy M5

As a more affordable alternative, the M5 represents a great bang for the buck. A lower price means it is a go-to, solid option for a mom or dad looking for that kind of performance for less.

Willow Go

Willow Go offers plenty of extra features and a more robust build, and as such, it comes at a higher price point. For some moms, the ability to use milk bags and slightly more comfort makes the added price worth it.

Winner: If you are looking for greater affordability, Momcozy M5 takes the top spot. But if you’re willing to spend a bit extra for bonus features, the Willow Go is worth a look.

Conclusion: Momcozy M5 vs Willow Go – Which One Should You Choose?

The Momcozy M5 and Willow Go offer impressive features that cater to modern moms looking for convenience and comfort during their breastfeeding journey. But, Momcozy M5 is a lightweight breast pump with all the effective powers of a normal pump — it also boasts customizable suction settings and a lower price point — and is an excellent choice for moms that need a simple, portable, compact, and affordable answer to their needs.

If you want to take your pumping routine to the next level with an app-connected, portable pump with hospital-grade strength, then the Willow Go is the best choice and perfect for moms who prioritize tech and performance.

So, the best option between these two wearable breast pumps depends on your pumping style and preferences. If you prefer a more stylish, hands-free option that excels in appearance and functionality, then the Momcozy M5 is the one for you.

But if your priorities are having top-of-the-line features — app control and better suction power — the Willow Go might be the best fit for you. Both are great products, and when it comes down to the Momcozy M5 vs Willow Go, it’s really about what will fit your lifestyle and pumping needs the best.
