Thank you for viewing. Since the accessories for this product are missing, I cannot confirm its operation, so I am selling it as junk. One unit is missing the battery cover. Please see the 10th photo. I am asking those who can use it for parts or repair. I will ship it as is, so please check carefully before considering a purchase. ※Included items: Main unit x 8 Software x 4 I am also selling on other flea market sites, so please be aware that I may suddenly delete the listing.
