I got this model as a Christmas present for my boyfriend and his little boy who is 6 years old. The model came with a missing part, but when I contacted Overstock, they have quickly resolved the issue. The number to contact NSI customer service is 1-888-425-9113 if in case anyone is missing a part. The engine actually works and my bf and his son had a fun time building it. :)
My grandson loves this and is having so much fun with all of the fun science stuff he can do with it for his inquiring mind. I was worried it might be too young for him, age 11, but it isn't! Great buy!
Ordered this as a birthday gift for my turning 8 year old grandson. He could not wait to get the box opened & get going on some of the different activities. He actually took it along to the park that day & started w/the dinosaur dig activity. He was happy for hours working on some of the activities all by himself & others he did need guidance & help. All in all I think it is a great gift for young children that love or have an interest in science.
My son is two going on three and I've been looking for a fun activity to help him work on one to one correspondence since he can count to one hundred already with very little help and he can recognize a lot of numbers already. This puzzle set is PERFECT, as it catches his attention because he loves puzzles. As long as I explain each step to him as we go along, he's been doing excellent! I love that there is an instruction sheet with many different ways to use the puzzles!
