Will this brick melt or leak if I leave my car parked in the sun?

Polyurethane gel is formulated to hold its shape in heat. It won't melt into liquid like some air fresheners, but extreme heat will accelerate fragrance release — keep it away from direct dashboard sun if you want slower output.

How long does one brick last before I need to replace it?

Depends on cabin size and ventilation, but most drivers get 3–4 weeks of noticeable scent from a 200G brick. You'll smell it fade gradually — that's your cue to swap it out.

Does this come with a vent clip or mount?

The air freshener brick itself is included — mounting hardware or clips are not confirmed. Check your existing vent clip or dashboard mount compatibility before ordering.
