    • 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! ... show more

    • Takes a while to assemble but I enjoyed it.
Fun to build (if you're into models). Works well once assembled.

    • Good product, most kids will need some help in assembling it. But it works if you get to the end!
Bought this twice - once as a gift for another kid and then again for my son's birthday. It is pretty cool and functional - not really easy to put together. My mechanically-inclined ten-year old was able to figure out most of it on his own, though some sections were a little confusing and it does take a bit of dexterity to get some of the pieces figured out. Instructions are mostly straightforward, but you do really need to ensure you read them correctly (mostly diagrams and numbers, not words). Overall a worthwhile gift - but plan on providing some not insignificant adult supervision to help build it. BTW beware not to accidentally throw away the hydraulic oil! It looks like a dessicant pack, but it is not, and you need it! Finally hand is capable of picking up things like cups of water, etc. ... show more

Good quality And so much fun!!

    • Very cool
Great for gifting, there are some steps that may require an adult. The pieces need to be cut out and burs removed from edges and that requires sharp scissors or a blade depending on age that may require assistance. The hydronic components also require lubrication and precision cutting of tube. Overall it’s not very difficult and it’s fun and silly as a toy that you can have fun with for awhile. The instructions include stories that are fun for kids too. Definitely recommend ... show more

    • 14 yr old loved it. Needed family's craft knife, small head screw driver, and cutting board.
14 yr old grandchild was ecstatic when they opened this present. They are an experienced Lego builder, but hadn't run across a project where the pieces had to be cut apart. Each color was cast in a sheet, with connecting thin plastic. For instance, all the black pieces were connected together. Same with the blue, yellow and white. Some other parts, like the hydraulic cylinders and small screws, came in plastic bags. Following the diagrams, they cut loose each piece as it was needed, and not before. A parent emphasized that it was important not to over tighten the screws. For a somewhat younger person, an older one could act as an assistant in separating the parts as needed. Assembling the hand is a good exercise in focus and patience in following the steps. It was fun for the 14 year old to take time and tackle this challenge. It took him something like 4 hours. Taking breaks reduces stress for those susceptible. The hand is adjustable in several ways, including being able to attach the fingers in different places. Grandchild had fun testing the hand's functions and abilities. ... show more

    • Not as easy as expected.
Ok toy. Do not recommend for 12 or younger. Very hard to understand directions, some are not clear. So, if your up for a challenge, I do warn you may rage quit. Overall not bad.
