Perfect STEM Gift: Fun and Educational Mega Cyborg Hand Kit!
I bought the Thames & Kosmos Mega Cyborg Hand STEM Experiment Kit as a Christmas gift for my 9-year-old son, and it was a huge hit! From the moment he opened it, he was excited to dive into the building process. The instructions were clear and easy for him to follow, and he managed to assemble it mostly on his own, with just a little guidance. Watching him figure out how each piece fit together and seeing his pride in completing it was priceless. The kit provides a fantastic hands-on learning experience, teaching mechanical concepts and the basics of hydraulics in a fun and engaging way. Once assembled, the cyborg hand is incredibly cool. It fits comfortably, works smoothly, and my son has been having a blast testing its capabilities, like picking up objects or pretending he's a robot. The fact that it’s adjustable for different hand sizes means he’ll be able to use it for a long time. This STEM kit is not only entertaining but also educational, sparking curiosity about engineering and science. I highly recommend it for any kid who loves to build, tinker, and explore how things work. It's a gift that keeps on giving!

Challenging but Fun Build! Perfect with Adult Help
We bought the Mega Cyborg Hand for our 7 year old, and it has been such a fun and engaging project for our whole family. Building it together has been a great experience, though I would say a 7 year old definitely needs adult help and guidance for some of the steps. There are certain parts where an adult is required, but that actually made it a really enjoyable hands-on project to work on together. Our 10 year old also loves fiddling with it, which shows how well it spans multiple age ranges. The instructions are very clear and thoughtfully laid out, making the build feel much less intimidating. I especially loved that some pages in the manual include fun comic style stories and interesting facts about the physics behind how the mechanics work, it’s a great educational touch! We have absolutely loved this purchase for the value and are excited to finish building it and start using the hand. Highly recommend for families looking for a meaningful STEM project to do together. Age range: 7+

Great, maybe age 9-10+ if you want them to do it independently
This was awesome!! My kid needed something to keep himself busy this did the job. He’s 6 so did need more help but didn’t mind it. It turned out so great and could use it as a time to teach how hydraulics work. Great quality little large for his age but again. He’s younger than one might get it for. It is very complex and a little harder to screw the screws in but we loved the quality time.

Challenging to put together - but fun.
This is a pretty neat hand. It took my husband a good two hours to put it together though and he is a very handy person. Definitely have to follow the instructions step-by-step if you want this to work. It was bought for my 6 year old and there's no way he would have been able to put it together. But he is proud of it and likes to play with it.
