Listing will be removed on November 20th. Cooling fan attachable to a helmet, providing a comfortable work environment. I am selling it because my work environment has changed and I no longer need it. I used it until this summer, so the operation has been confirmed. I used it for a year, but the battery life is still good. There is some minor dirt. The accessories are only those shown in the photos. Returns are not accepted to prevent product switching. Thank you for your consideration.
