Da Vinci Rolling Ball Timer - Da Vinci Machines Series Kit by Academy #18174

Beautiful, interesting-to-watch mechanism. Awesome shelf/coffee table conversion piece. I also plan on using it as a game timer, instead of those cheap sand timers. Love it. Directions were in Korean, but it's easy enough (and fun!) to build with just the pictures.

Just built this thing and at first it didn’t work but I fiddled with it some more by taking it apart and tried rebuilding it again. There trouble may have been with how I placed the arm on or I may have placed the final gear in the wrong direction. Anyway, it’s fixed and it works now. So I guess this is challenging.

Chinese box, CHINESE assembly instructions and made from a VERY cheap plastic. Not worth the money!!

Instructions were in Korean! Diagrams were clear and unambiguous making it easy to understand how to assemble the model.

Buyer Beware - When I ordered this product I did not realize the box and instructions were in another language (Korean? Japanese?). The picture of the box was not shown and nowhere was it mentioned that instructions were not in English. I think my grandson will be able to put it together using the pictures but what a downer giving him something he could not read! Hope it works after assembled.

The construction was a bit off in getting it to work.

Great model, fun to build.

I guess I didn’t pay that much attention to the pictures. They were screen shots instead of actual product. I returned this and found the actual product in English at hobby lobby for lower price.

Produto de qualidade e funciona mesmo depois de montado!
