Solar Power Energy DIY Kits Brick Block Wood waterwheel Child Educational 3D Wooden Jigsaw Puzzle Toy (W150) by Sansutech

This was a birthday gift for my 4 year old. When I opened up the package the key component of set-up was missing. Product is totally useless without that required bolt.Its total waste of money. Please stay away.

MUST KEEP UNDER HOT SUN LIGHT. WORKS WELL.

Have to use intense light to get the motor to turn.

Good
