Review: highly recomended - Bought it for my 6 year old son on his birthday. This is his favorite among all the other gifts that he got including lego. He can assemble it mostly by himself with occasional help. Instructions is clear. Though the finished models do not always work smoothly, it has excellent play value and teaching moments. There is an issue wth durability mainly due to the material being thin. But in their website they have the option where you can ask for the parts misplaced/broken and they will send them promptly, free without any question asked. For my case they even send some extra. All in all, excellent toy.
Review: Good product, keeps your kid busy for a few hours - Evey easy to assemble, simple instructions book. Keeps your kid busy and curious for a few hours everyday. Has to be handled well, one of the long side strips broke.

### ⭐⭐⭐⭐⭐ Amazing STEM kit
*by S***I on 6 October 2022*

I bought this kit for my nephew, I am really happy because he just loved it. He is a kid who loves experimenting and trying new things, this is just perfect for him. Best thing this kit comes with a manual with pictures, if followed steps by steps its very easy and interesting too. Also no tools are required to assemble so no mess. I must say it's a great kit for brain development. Helpful to engage kids and avoiding screen time.
