How do I install this — does it come with a hanging clip?

Installation hardware not specified in the product listing. Confirm whether mounting clip or chain attachment is included before ordering if you plan to hang it. If not included, the brick can sit on a dash, seat, or floor mat.

How long does one brick actually last?

Duration depends on cabin size, ventilation, and how often you run the AC or open windows. Solid bricks like this typically need replacement every 3–4 weeks in regular-use conditions, but may last longer in well-ventilated or larger vehicles.

Will this scent clash with other cabin products or air fresheners?

Strawberry is a sweet, fruit-forward scent. It works on its own, but combining it with other active fresheners (cologne sprays, vent clips, etc.) in a small cabin will intensify the overall fragrance. Use one product at a time for the cleanest result.
