Just arrived today. I'm not a professional, but I've checked the operation and I think there are no issues. Please understand that this is not a perfect operational check. Also, the battery is bad, but the power turned on while charging. The battery is missing. This is a used item, so I think it's best to consider it as junk. Due to being treated as junk, please understand that no claims or returns are accepted. This product includes the main unit only. Please ask any questions in the comments! ※Caution※ Shipping has some leeway! I try to ship on the same day if I can. This product will be shipped via Nekopos!
