Love this set! This was our first Engino brand car we got and totally loved it. The pieces were super easy for a 6 year old and she was able to put this together completely on her own without instruction for a good hour!What an amazing product! I checked out their website as well, and they have quite a variety of different building kits for different ages. If you haven’t thought about what to get your kiddo for Christmas, I HIGHLY recommend getting into the Engino brand.The box was well designed with one simple book and different pieces in multiple bags. The book also gave really good information learning about the individual item so it turned it into a fun building class.To top it off, it comes with a 3-D CAD rendering instruction step-by-step app we downloaded to my phone in case we lost the booklet it came with. Engineers use CAD for developing plans, so to teach a 6-year-old how to follow CAD directions by zooming in/out and developing a final deliverable with visual steps to follow is probably the coolest underappreciated thing I’ve seen in a while.My daughter he was super excited to get this set and within an hour, she had her first complete build! These are not teeny tiny like you would expect with Legos, but they do require some complexity in piecing them together and it’s SOOO rewarding. They have different models for different age ranges too some sets for 3+ year olds!If your kiddo is too small and gets frustrated easily, it would require a lot of your attention to keep them focused, and to ensure they don’t bite the pieces. For a six-year-old, this now became a product I donated to our local primary school. My daughter loved it so much that she wanted other kids to experience putting it together and feeling good about it!Well done, Engino! Maybe the company will reach out to me and I can be their school advocate!I wish I could give these sets 100 stars for first graders!
