We bought for our son to 5th birthday this set and love it! Even now he lies down the parts and tools it needs alone cope. When assembling it needs help, of course, but that's not a problem since even mom and dad have in assembling joy. And the best part is that it does not come after a week in some corner into oblivion because it all the older he gets more and more alone made can! Conclusion: Finally a reasonable, educationally valuable gift that is fun !!
