UGEARS STEM Differential Model Kit - Creative Wooden Model Kits for Adults, Teens and Children - DIY Mechanical Science Kit for Self Assembly - Unique Educational and Engineering 3D Puzzles with App

Good initiatives in learning the fundas.

I bought this product from a store (not Amazon). It is an extremely interesting concept, but the product doesnt 'line up' like it's supposed to. The size of the base is too small and there is no way to get the larger side gear wheels to sit atop it and work.

図解が優秀。プライアと金槌は準備必要。部品に塗る蝋が付属している。

I've never made anything before model wise but the instructions were easy to follow and everything you needed to build it was included in the box. There are spares of some of the parts just in case they got broken or lost maybe. My favourite part of the build was popping out the pieces and then my husband actually put them together so it was a nice lockdown project for both of us to complete. The pieces were very well constructed and overall the model works and looks good. Very impressed for the price and would purchase some of the other models from this brand.

Molto semplice da montare. In un paio di ore, se la si prende con comodo, ed è finito, bel soprammobile per gli amanti della meccanica.

I've always wondered how a differential assembly works in steering a car, and at last I understand it! I am a committed fan of these superb models, and cannot recommend them highly enough. Buy with confidence.

Quality is very good, functionality is great. Not the easiest build, needing some parental support but fun to do. Some model building experience helpful.
