First of all - this is a great toy! BUT it is not suitable for children - its more like a geek toy! It´s fun to play with! Works great and has a fantastic mecanism!
The manual is not really right! The manual says you have to set the button on the saucer in the middle position to charge - this is not true. My saucer only charged when the button was in the OFF-Position! Than the light changed to green and the charging process begun! So be aware of that!
Other Thoughts or Suggestions:
Over all its a great toy and a reasonable price! Buy it and have fun!
