Our 12 year old had fun with this kit, so far he has made one of the boat projects. He really enjoyed putting it together, the only thing he asked for help with was folding the boat portion as the instructions weren't very intuitive. However I'm sure he would have figured it out himself.

I got this for my son for his birthday and it was really cool but the parts break very easily such as the hydraulic crylinders. most of the arm worked but i dont think this is meant for 10 year olds and i think the motor skills requierd for this is at least of a 12 year old. The Levers were also werid to use as some were very stiff and some were easy to push. I also have to order a new part beacuse one of the hydraulic cylinder nozels broke when trying to fit the tube to it.

This was a present bought for my 10 year old grandson.
Terrific choice in that although I found it was generally beyond his technical ability and fine motor skills, he was totally engrossed as we assembled it together and totally mesmerized by the arm's ability to be operated by levers remote from the arm.
The 'box' suggests that this challenge is for those 10+ years old. It would be a very remarkable 10 year old who could put this together unaided. But then, working on this project together was probably closer to the rationale for buying it in the first place.

It's fun to build and play with, but parts break easily. Thankfully it's just as easy to get replacement parts.

My son (8) got this as a Christmas gift and it was easily the most excited over this gift. He and I spent time over the next couple mornings building this cyborg hand together Watching it take shape. It is very neat now that it is complete
