Tested and confirmed to be working. Includes 3 AA batteries. No instruction manual. Although there are no six screws, it can be easily installed. Everything in the photos is included. Disinfected. It works without any problems and is in good condition, but please be aware that this is a toy that a baby has used. I will pack it with bubble wrap in an outer box to prevent it from getting wet.
