Great for the mature kid
My 10 year old boy LIVES this but needed quite a bit of dad-help to put it together exactly right.

Instructions are overwhelming
It took me two days to put together and the instructions were complicated. My grandson likes it for the most part and the only issue we have is that the button that open and closes the claw is a bit difficult for him to push.

Excellent challenge
As grandparents, we scored big on this gift for our grandson. He enjoys the challenge, having risen above the challenge of even the most intricate Lego products. We will plan on buying similar items for a couple more years.

Nice product
Bought as a present for 13 year old who found it interesting and liked it. He went wrong on one of the steps but he worked it out and carried on. Nice quality.

Bought it for a grown man haha
My boyfriend is a whiz at puzzles, every year for his bday I try to find an impossible puzzle. Ten years I've been trying and this one finally challenged him. He completed it in one sitting on a rainy day (like 6 hrs) with movies playing in the background, but even he said it was hard. I can't imagine a kid could complete this without help. I'm pretty sure we'll take it to the goodwill, as the toy itself isn't all that entertaining for a 40 something man, but I was giddy that I finally challenged him. Absolutely would buy something like this again!
