I purchased this to replace the same equipment at an acquaintance's store, which was reported to be broken. However, the equipment was actually not faulty, so replacement was unnecessary. The box has been opened, but the item has not been installed. Please refrain from purchasing if you are overly concerned about this. The lowest price online is 15,953 yen, but I am selling this at a bargain price for disposal. Therefore, I am unable to offer a discount.
