We purchased this for our 5 year old who is fascinated with space and electricity. There are maybe 2 or 3 spots in the directions (a step by step book similar to a big building brick brand) that we're quite unclear. One of the rover's doesn't move, but if they had included one more motor and one more battery piece, everything would have lights and motion.Some of the pieces were too difficult for his hands to put together, but we did it together, and he was so proud.The circuits are easy to connect because of the lines provided on different pieces, but there's not much explanation, so the educational aspect isn't too strong here.All in all, though, we loved that this was a nice combo between Lgo, Snp circuits, and a play set. It was a great toy for our son.
