I received this from an acquaintance, but I haven't used it, so I'm putting it up for sale. I don't know how much the person who gave it to me used it, but I have confirmed that it works. There are no accessories such as the box, instruction manual, or strap. The battery is included so you can test it immediately, but it's likely worn down, so I don't know how long it will last. You will need to replace it yourself when it runs out. Since there is no original box, I will make my own packaging. Please refer to the 2nd, 3rd, and 4th photos. Please refrain from purchasing if you are sensitive to used items.
