EUDAX DIY Dynamo Lantern Educational STEM Building Toy, Hand Cranked Power Generator,Generators Science Kit, Light Bulb Science Experiments Kits for Kids Age

What you see is what you get, exactly as pictured, not difficult to use once completed. It took way longer than expected to assemble by an adult husband, assisting a young child as a do-together project. Our small son really enjoyed playing with the crank after it was done- he's fairly careful not to destroy things, and had a great time. This requires patience and a joy of put-togethers or you will NOT enjoy this product. It's way smaller than pictured so good vision and good dexterity is a must. Came with a really nice screw driver and a few extra parts. :)

This was a little difficult to assemble for my 9 year old, but it was an awesome activity for him and grandpa! The instructions aren’t very clear. But the final product is fun and putting it together is definitely an educational learning experience. Total assembly took about an hour- mostly because the parts were so tiny and it wasn’t clear which screw to use where. All in all, this is totally worth the $10 price tag.

Nice everything but I think they send two motors , should be one motor and one generator ,assembled it correct and didn’t work

Pretty good, useful components but not so good instructions. Some parts were difficult to place

Excelente

Buyer beware. Pay special attention to the pic that notes the dimensions of this product... it is painfully small, which makes it all the harder to assemble and work with. Furthermore, everything in this kit is of the cheapest quality imaginable. The screws strip super easily rendering them useless. the plastic gears do not mesh well and constantly chatter and skip. The blue baseplate, which anchors everything, flex to an unacceptable degree... thereby making the gear clearance even worse. The wires are the smallest gauge imaginable and break instantly if you try to strip them to expose more conductor. The instructions do nothing other then show you a general picture and say "make it look like this". And finally, worse of all, the large gears are not keyed onto the shafts in any way... they therefore quickly wear-out and slip on the shafts when the shaft rotates... rendering them useless. This sad excuse for a kit is, without question, the most disappointing purchase I have ever make on AMAZON. 100% do NOT recommend.

Easy to assemble! It worked perfectly when finished! Budget friendly and Great for learning.

Super disappointed and so difficult to assemble with awful instructions as many have noted. We finally got the fan to work but not the light. My grandson is enjoying it but it’s not a product that will last long. . I know it was only 10 bucks and you get what you pay for but the time spent assembling makes it not worth it.
