  • EXCELLENT
My 17 year old son loved building this little robot. It is well made with quality parts that snap together securely. The instructions were very clear. Once built, the little guy goes and runs perfectly! Definitely recommend this set.

  • Was missing parts
My grandson’s kit had missing pieces, had to modify the design to accommodate. The app has little instructions. Overall kit works, the manual was hard to follow as drawings for specific parts were not defined enough and led to some reassembly. Overall a cute kit but not worth $50.
