⚙️ Hardware Setup, Adjustments & FAQs

❓ My phone isn't magnetic, will the cooler work? cfg_01
Yes, but you will need a compatible magnetic ring. It can be attached to your phone case or directly to the device (if it's not glass or a material that could be damaged). The cooler will attach to the ring.

⚖️ Seller Warranty & Marketplace Dispute Conciliation

Contact support for warranty service if the cooler exhibits manufacturing defects, such as fan failure, internal circuit problems preventing operation even with an adequate power source and clean connections, or if the magnetism is demonstrably weak from the factory, showing no signs of misuse. These are defects not resolvable by the consumer.
