We have not handled this item. The figures above are the seller's record on AliExpress, not our assessment of quality — see how we pick. Delivery time and shipping cost vary by seller.
Material: Ceramic
This is what the seller states, and it is not something we can verify. The distinction that matters most in cheap imports is between a material and a coating: "stainless steel" and "stainless-plated" are different products, and the second one rusts where it is scratched. Where the listing photographs an edge or a cut face, that is the useful image.
Interface: BLUETOOTH
The connector standard decides what this works with. Worth knowing that a physical connector and the protocol running over it are separate things — a USB-C socket does not guarantee fast charging or video output, and an IP rating on the housing does not extend to the cable entry unless the listing says so.
