Thank you for viewing. This is a seat cover with a built-in fan. It draws power from a cigarette lighter socket, and the fan speed can be adjusted with a button switch. The seat and backrest have mesh and fans, which help to release heat and prevent stuffiness. The quantity is 2. I'm selling these because I'm changing vehicles, even though I've only used them for about 3 months. The condition is good. However, since they have been used, there are some minor scratches and scuffs. If you have any questions, please leave a comment.
