The lid that covers the computer components was not secured. The installed Windows 10 program could not be activated.  No product key was provided. The keyboard was inoperable as some keys stuck when pressed and the space bar would not work. When the space bar was depressed, several keys depressed with it. There was some residue of a glue-like substance on the keyboard. The USB cable for the keyboard was bent closed preventing plugging it in. There was no way provided with the computer to report the problems. Once installed, the operating system worked OK.  I had to get a new keyboard in order to use the computer.
