Will this damage my vent louvers?

The clip is designed to grip without deforming or cracking plastic vents. Test-fit it on your vent first—if the louvers flex excessively or feel at risk, do not force it. Most standard vents will accept it without issue.

How long does the scent last?

Marine squash fresheners typically hold their fragrance for several weeks with normal cabin ventilation. Once the scent fades, you can replace the unit or refill it depending on the design—confirm with the supplier if a refill cartridge is available separately.

Can I move it between vehicles?

Yes. The clip-on design lets you remove it and mount it on any compatible vent. Just clip it off and reinstall on your next car's dash vent.
