Purchased around 2022 and used occasionally, but haven't used it much recently, so I checked its basic functions. I confirmed that it can play Blu-ray discs without any problems. I also confirmed that it works even when not plugged into an outlet. Although it's difficult to see in the photos, there is some dirt, especially noticeable on the ear parts and the circular button. It looks like yellowish paint from a shelf has gotten on it. I also confirmed that the child's remote control works. However, I will send it with the batteries removed. I'm not sure if they're dead, so the adult remote control may not work. The accessories, including the microphone, also have some dirt. I haven't connected it to a TV via HDMI, so I haven't confirmed that function. I'm selling it because I've switched to a tablet. If you have any concerns or want me to check anything, please leave a comment. World of English Blue ray
