I purchased this here and used it for about two months. Now that I'm on track, I'm selling it. ・Functions properly. ・The year on the back was originally peeled off, so it's unknown. ・The batteries currently in use will be included. ・The shipping label will be affixed directly to the outer box. ・There are some minor stains from use, but it's generally clean. I will wipe it down with alcohol before shipping. Thank you.
