Why did I try an extender clip while wearing a long puffer coat?
In winter, thicker clothes made the seat belt feel like it was pressing against my stomach. I was curious whether that tight feeling would change, so I tried the provided Migijae seat belt extender clips.
What were the price and package contents like?
At the time the original post was written, the price was ₩13,900 for two. It said buying four would be a little cheaper, although no exact price was listed. The design was glossy black with no car-brand marking.


It is designed for one-touch installation, so the connection process looked simple.

The box contained two clips. I liked that there was no excessive packaging.

The product description introduced a high-gloss finish, alloy material, and reinforced alloy pin as features. What caught my eye was its simple shape and shiny finish.

When I opened the box, the two were placed side by side. The simple setup suited my taste.

After taking one out, I could see the glossy surface, and its lower part looked similar to the end of a regular seat belt.

What was it like to connect and remove it in the car?
There was a round button on top of the clip. Like the red button on a regular seat belt buckle, it releases the connection.

In the car I tried it in, it fit well even when I turned the clip front to back.


Once the clip was attached, it seemed to open the angle slightly and create some space. It clicked into place when connected, and I pressed the car's regular red button to remove it from the vehicle buckle.

Connecting the seat belt to the clip was simple too.

After connecting it, I put on my long puffer coat and wore the seat belt.


Did it change the pressure around my stomach?
Because I was wearing a long puffer coat, the before-and-after difference did not show clearly in the photos. Still, it felt more comfortable to me because my stomach felt less constricted.

At first, I wondered whether the extra length of the clip alone would make a difference. Once I wore it, the straight section of the clip made my stomach feel less pressed. When I pulled on it by hand, it did not come out unless I pressed the release button.

Did I check the back seat and child-seat use too?
I also looked at the rear-seat buckle area. I came across information saying belt extension may be needed when installing a child seat, but I did not install a child seat myself and did not have sample photos.

The original post introduced this as a product compatible with front and rear seats and all vehicle types. However, I did not personally check it in every type of car.

The original post also mentioned that the clips can be connected to each other. The change I personally noticed this time was less pressure around my stomach while wearing a long puffer coat.
