The dark black color was subtle, and I liked the glossy design. ![Dark-black seat belt extender clip with a high-gloss finish](https://img.superchart.com/images/errify-seat-belt-extension-clip/errify-seat-belt-extension-clip-05-113o4-900.webp) *Seat belt extender clip described as compatible with all vehicle types* The overall length was about 9 cm, and the front plate was about 3.8 cm long.

You attach the clip between the existing seat belt and the car buckle. When I tried it, the process felt simple. ![Connecting the existing seat belt and the extender clip](https://img.superchart.com/images/errify-seat-belt-extension-clip/errify-seat-belt-extension-clip-07-bey2d-900.webp) To remove it, I pressed the round part while pulling it out. ![Using the release button on the seat belt extender clip](https://img.superchart.com/images/errify-seat-belt-extension-clip/errify-seat-belt-extension-clip-08-v9suz-900.webp) ![Process of attaching the seat belt extender clip](https://img.superchart.com/images/errify-seat-belt-extension-clip/errify-seat-belt-extension-clip-09-16cr0-900.webp) ![Connecting the seat belt extender clip to the car buckle](https://img.superchart.com/images/errify-seat-belt-extension-clip/errify-seat-belt-extension-clip-10-1nvwy-900.webp) ## How did they feel over a thick winter coat? Once attached, I did not notice any wobbling. The biggest change was that the belt felt less tightly cinched. It felt as if there was a little more room across my chest, and it was comfortable even with a thick winter coat on. ![Wearing a seat belt for a before-and-after extender clip comparison](https://img.superchart.com/images/errify-seat-belt-extension-clip/errify-seat-belt-extension-clip-11-hbpbr-900.webp) ![Seat belt shown for an extender clip comfort comparison](https://img.superchart.com/images/errify-seat-belt-extension-clip/errify-seat-belt-extension-clip-12-1ra3m-900.webp) I also took photos before and after wearing it.
