Have you ever heard about Gaksimil G1 breast pump?

“Huh…what brand is that?”

That was my initial reaction when Adale Lim from MyMiracleBaby approached me to do this review.

After a quick search later, I found out that it is a Korean brand that is just growing in its popularity.

Wow.. a new breast pump brand…!

Are you curious how this new breast pump performs?

Find out more in this detailed Gaksimil G1 review.

*I received a Gaksimil G1 Dual Breast pump in exchange for the review (All opinions are my own).

Highlights of Gaksimil G1 Breast Pump

1.Hospital grade with maximum suction at 440mmHg.

When I first read its detailed specs, this number really ‘wow‘-ed me.

Is this for real?

This is much much higher compared from other typical breast pumps (which is usually at 250 mmHg or 300 mmHg).

But I was quickly convinced when I tried this pump for the first time.

For me, suction level 4 (out of 9) is already strong enough, I didn’t dare to try higher.

2.Closed system with a unique back flow protector design

I always love closed-system pump because it prevents the breast milk from flowing back into the pump motor.

And the cool thing about Gaksimil is they have a super smart back-flow protector design (vacuum compressor type instead of the typical piston type) that will make your breast pump stops automatically once it detects back flowing problem.

This makes this breast pump has ZERO chance to get contaminated, NO germ build up, leading to a very durable pump motor.

Additionally, since this is a closed system design, this breast pump can be safely shared by multiple users (provided that they own their individual milk collection kits).

3. Smooth suction pressure

This is because it has a unique diaphragm design that vibrates 2500 times per minutes.

4. Super duper quiet

This pump is awesomely quiet with noise level lower than 45 dB.

It barely makes any noise, all I can hear is just a purring sound, which is super great if you need to pump next to your sleeping baby or pumping in your cubicle at work.

5.Suction and speed can be adjusted individually

I love customization especially when it comes to the suction speed.

The fact that Gaksimil G1 breast pump provides 6 different speed levels and 9 different suction levels (54 combinations), that means it can be used by a vast range of mothers who may have different suction/speed preferences. Here’s how the speed looks like for each different level.

Speed cycle	No of cycles per minutes
1	37
2	35
3	33
4	32
5	30
6	28

Other pros:

Single / dual pumping

This breast pump can be used for both single and double pumping, which is a nice feature to have, especially if you plan to pump at one side while nursing your baby in the other side.

It comes with a let-down mode that will help you to achieve your let down (more about this below).
Nice and sturdy collection bottles

Nothing puts me off more than flimsy collection bottles that easily topple down and spill my precious milk.

The bottle that comes with Gaksimil is sturdy enough to stand on its own, even with breast flange attached to them.

Fits standard-neck bottles

Don’t ever worry about needing to buy special bottles for Gaksimil pump. Its breast shield connects to standard-size (narrow-neck) bottles. That means you can use your existing Medela, Ameda, and other narrow-neck bottles.

The Cons:

The let-down mode cannot be adjusted (in terms of suction strength), so you will be stuck with only one option.

Additionally, the way the breast pump works in massage mode is slightly different from other pumps.

A typical let-down mode is usually characterized with a fast, low-strength suction that mimics baby’s initial suckling.

Gaksimil’s let down works differently.

It starts with a rather mild-strength suction, followed by two low-strength ones.

It’s kind of awkward because I’m not used to it. But again, perhaps it is something that you will get used into once you start using the pump regularly.

Limited breast shield size

Currently Gaksimil only has 2 breast shield sizes, 27-mm, which is the default and 30-mm (for large).

It would be great if Gaksimil can come out with a smaller breast shield size, such as 21-mm and 24-mm.

Initially, since its breast shield is a two-piece design (similar to Medela), I was hoping that I can use Medela breast shield for smaller size.

However, upon trying, I found that they are not fully compatible. The 21-mm breast shield fits the breast shield connector poorly, but the 24-mm one has a better fit (though I won’t said it’s in perfect alignment).

Having said that, I heard that one mom managed to use 24-mm Medela breast shield with Gaksimil without any problem.

So I guess the compatibility really depends on the breast shield size.

Very minimal display

There’s no LED display in this pump, except one little screen that shows you only one number, either the current suction strength / speed level. Too bad for such a nice breast pump.

To check what this number is, you just need to check the light indicator just next to the suction button /cycle button adjustment (see the picture above).

The pump starts in expression mode (not so intuitive).

You need to press the massage button to switch it to massaging. A light indicator next to the massage button will tell you that whether it is in expression mode (light off) or massage mode (light on).

5. Bulky and no built in battery.

Yes, this is a bulky breast pump weighing about 1.15 kg and measuring 24.4×15.6×12.1 cm.

However, I believe the bulkiness serves as a proof that hidden inside is a powerful motor that leads to longer durability.

Also, since it does not have any built-in battery, you have to pump close to a power source, which makes it less portable.

If you are looking for a slimer and portable version, check out Gaksimil Slim or Sense.

***What about efficiency? Can* Gaksimil *G1 empty breast efficiently?***

Since I just recently weaned my daughter, I asked my breastfeeding friend to try the pump to see how effective it is.

In 10 minutes pumping, she was able to express a decent amount of milk, though slightly lower than what she used to get with her usual pump.

She did however, became impatient with the let-down mode and decided to switch to expression mode before achieving let down, and I guess that explains why she got slightly less milk.

Final Thought

This breast pump is great for mothers looking to establish and build their milk supply as well as working moms looking for a reliable and discreet breast pump to accompany their breast pump journey.

And one more thing, if you prefer strong suction (just like me), you’ll love this pump.

At the time of writing, I have no luck finding other Gaksimil reviews, except a short comment in ParentTown. But I believe, as soon as this pump became a more popular, you’ll see more and more positive reviews about Gaksimil G1.
