This item was received from an acquaintance. My animal-loving daughter might enjoy it, so I brought it home, but her reaction wasn't what I expected, so I've had it in the office for a while. I believe it functions without any particular problems. (There may be some slight rubbing sounds from the moving parts occasionally; I'm unsure if this is due to a lack of oil or is just how it is.) I had Sony check the current status based on the serial number, and they informed me that "it is not currently subscribed to any active services." Therefore, it has not been initialized, and is not linked to the aibo app. I was informed that a plan subscription is necessary for normal use. As you can probably tell from my listing, this is not my area of expertise. I will answer questions to the best of my ability, but it may take some time. Product Contents: aibo body Charging pad Charging adapter Ball That is all. There is no SIM card, product key, outer box, or related documentation. There are scratches on the nose and paw pads. There may be other minor scratches and scuffs. Please note that the battery life of the main unit is not covered by warranty. (I've seen that some people replace it after about 3 years.) After purchase, please contact Sony Support (toll-free 0120-30-2629) and inform them that you have received the aibo. Then, subscribe to the "aibo Basic Plan." A new SIM card will be sent to you, which you should insert into the aibo's belly and perform the initial setup. If you have any questions, I can upload additional photos, so please let me know.
