could be tricky to fix it
it has to be accurate 100% or it will not work. No exactly as expected

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.

Good quality plastic material. Assembled easily, gears meshed well. Product worked well after assembly.

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

Nice project. But to many parts and a little hard to do.

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.
