Due to defects and some unconfirmed operations, this item is being sold as junk. Please be aware of this beforehand. Price is negotiable, please inquire. Everything in the photos is included. Please check the photos for any missing items. Defects: ◯ Brightness adjustment is not working. The adjustment dial does not respond when turned. It is stated that brightness adjustment is possible through the app, but I have not confirmed this. ◯ It seems to be a built-in battery model, but it does not turn on unless it is connected to a power outlet. It is unclear whether the battery is dead or if it is not a built-in model. (I apologize for my lack of knowledge) ◯ There are sticker marks and scratches on the outer box. Power-on confirmation: Light on confirmation LCD screen lights up confirmation Other functions not confirmed I have not confirmed the operation by connecting it to a computer. I was given this item due to the brightness adjustment dial malfunction, but I ended up not using it because it was too troublesome to install the app. Although there is some wear and tear on the power outlet part, the main body is relatively clean. Please consider this item with the understanding that there are unconfirmed operations, defects, and it is junk.
