It runs under 30dB on the first speed setting. That’s quieter than the office around you.

No. The brushless motor runs at under 30dB. It’s not working hard enough to generate heat. After 30 minutes of continuous use it remains cool to the touch. The airflow direction is outward, so the output is always cold air moving away from the clip, not heat conducted into you.

Everything else you tried used passive cooling. Static cold that sits still. Your body’s cooling system needs moving air to complete the process. Without it, both cooling channels stall. That’s why the flash dragged on.

Reva Air produces 61 °F/16 °C cold air, directed at your chest and neck. It works with your body’s heat-dump response, not against it. That’s the mechanism difference.

And if it still doesn’t work for you: 30 days. Full refund. We don’t deserve your money if it doesn’t.
