I gave this to the kids before Christmas since they opened it. Well that being said they both enjoyed putting this together and doing it together . No fighting is a first in our home. I wouldnt recomment this for children under 4 since alot of parts. My kids put them together easily and pretty fast. So I will say A+quality A+educational A+STEM
