It is not working at all.
This is a follow up to my previous feedback. You need a lot of sunlight and it should be perpendicular to the solar panel (!) to power the motor. Even with lots of sunlight and a turning motor, when you put the car on the surface (under the sunlight), it seems the power can not overcome the weight of the car and cannot push it forward. If you want to see some action, take the car off the table turn the car to be perpendicular to the sunlight and you will see the motor is working when you put it back on the table it stops. Anyway, after seeing this, I may give the product 2 stars instead of one.
Thanks
