Will these clip fit my dashboard vents?

These are designed for standard horizontal vent slats found on most vehicles. Test-fit one to your vent opening before fully committing — vent slat thickness varies by model year.

How long does the 1.5G gel last?

Gel lifespan depends on how often you run your HVAC and cabin air circulation. Expect several weeks to a couple months of noticeable scent before it depletes.

Can I refill these or are they single-use?

These are designed as clip-on units with a gel cartridge. Check the product packaging for refill availability — some buyers remove the clip housing to swap in fresh gel, others replace the whole unit.
