The power response is very poor, so this item is being sold as junk. If it can be powered on, it will function normally. The accessories are in good condition, so they could be used for parts. The built-in lithium battery is dead. A new one is included as a bonus, so please replace it yourself. Includes an unwritten warranty, instruction manual, driver CD, cables, power adapter, screws, rubber feet, and the original box. The cables, screws, and rubber feet are unused.
