This water power STEM toy kit from Thames & Kosmo was a hit with my 7 y.o son and he had lots of fun building and trying out the various water powered toys and had a lot of re-playablity. BUILD QUALITY - Probably one of the best things about this toy is its excellent build quality and the fit and finish of its interlocking parts. - We have brought other similar build it yourself STEM kits for our son in the past and almost all of them are generally plagued either poor quality parts or ill fitting components that not only are difficult for kids, but also compromise the structural rigidity of the toy - We had no such issues with this STEM kit , every component was made with high quality , thick plastic that fit together very well USING/PLAYING WITH IT - Our son was able to follow the simple instructions by himself and able build out the various toys. His personal favorite was the rocket car - The pump mechanism feels solid and is airtight - The performance of the toy depends on how much air you are able to compress/pump in the tube . Our son was had a bit of difficulty compressing the air too much as it required a lot of force and asked us for help because he wanted his car to go 'fast' DISLIKES None really FINAL THOUGHTS Overall is a a very high quality STEP build it yourself kit for kids that they will sure to love and would make a great gift for them. Highly recommended
