This car gadget plugs into a car's cigarette lighter socket and connects to your smartphone or other devices via Bluetooth, then transmits the audio through FM radio waves. It has a 5-stage folding mechanism and a USB output. You can play and pause music using the switch on the side of the device. I've used it for about four years, and it has no noticeable scratches. Operation has been confirmed. I plan to ship it via the "Nekopos" delivery service.
