I have performed a basic functionality check, but this is a used item, so no operational guarantee is provided. The controller has not been thoroughly checked, so please understand that it is being sold as-is. Please check the images for details on the exterior condition. Everything in the images is included. There is no internal data. I have not described the condition of the reading speed, sound, or button feel, as it is difficult to do so. This is a used item, so please refrain from purchasing if you are looking for a perfect product, are overly concerned about details, or have any worries. *The software used for the functionality check is not included. Please note that I will not respond to price negotiations without a price offer. After purchase, if you have no particular requests, greetings are not necessary. I will only send a message when the item is shipped, so please refrain from purchasing if you intend to leave a negative review because there was no greeting. Please be sure to ask any questions in the comments before purchasing.
