Yes. The core of the product uses N53 grade strong magnets with powerful suction. After repeated testing, even under severe bumps or sudden braking, the top cover will not loosen or fall off, ensuring safe use.

The hollow grid design significantly increases the air contact area and circulation path, allowing fragrance molecules to diffuse more quickly into the car's interior. Compared to closed or small-hole designs, the diffusion speed is improved by approximately 30%, and the scent distribution is more even.

The clamping parts of the K-M40 are fully wrapped in silicone, and the clip size has been tested for compatibility with multiple vehicle models, making it suitable for most horizontal and vertical louvered air conditioning vents. The silicone material increases friction to prevent slipping while protecting the vent blades.

A single solid fragrance disc (Ø32×8mm) can continuously release its scent for approximately 30-45 days under normal use. To replace it, simply lift the top cover (magnetic structure), remove the old disc, and insert a new one—no tools required, making the process easy and convenient.

No. The shell is made of high-carbon steel, stainless steel, or aluminum alloy, and undergoes surface treatments (such as mirror polishing, anodizing, etc.), offering excellent corrosion resistance and wear resistance, maintaining a metallic texture even after long-term use.
