I believe this is a model from around 2020, and the built-in content should be similar to current models. It also supports online connectivity via Wi-Fi. It runs on two AA batteries. Please note that batteries are not included. As shown in the photos, there are scratches on the front cover and some dirt around the screws on the back. One of the rubber feet on the back right is missing. The item will be shipped after being wrapped in bubble wrap. Thank you for your understanding.
