Extremely unstable operation. How about it for parts or repair? This is a junk item, so there is no guarantee of operation. Please be aware. There is no warranty or original box. The included accessories are what I have on hand, please check the photos. (Includes the main unit, pen, and dedicated cable) [Condition] The screen flickers or doesn't turn on. Sometimes the screen displays without any problems. Even when the screen is off, the function buttons on the pen and tablet can be used. I think it can be used as a drawing tablet at worst. It is recognized without any problems when connected to a PC.
