USB-connected accessory for a child seat. Includes a remote control. - Color: White - Type: Child Seat Accessory - Connection Type: USB - Control Type: Button Remote - Circuit Board: Visible Circuit Board Thank you for viewing. The circuit board of the remote control for the AirLove 4 Donut fan, which I used for one season, is broken. I think it's probably a disconnection, and I tried to fix it with solder once, but it didn't work. The rest is in good condition, so I would be happy if you could fix it and use it.
