Guests are saying
The cyborg hand kit offers an engaging and educational experience for young builders, particularly those interested in robotics and STEM activities. While many guests appreciate the challenge and the fun of assembling the hand, some express frustration over the complexity and durability of the parts. Clear instructions and the opportunity for parent-child bonding make it a worthwhile project, though it may require adult assistance for younger builders.

I was not optimistic when my son bought this because I was afraid he would get frustrated and quit. He did not. He completed it and was so excited to go around the house picking things up and handing them to us. The only thing I would recommend having on hand would be a pair of the nail clippers that look like pliers, they're small enough for kids to hold and to get the pieces out of the plastic forms they come in. My son was also able to easily trim off any sharp parts that remained from snapping the pieces out. In the end this was challenging to my son and fun to play with after.

Hard to build
It was so hard to build. It took me four hours. But the problem is that the robot's hand and fingers won't move. I'll have to reassemble it.

Absolutely amazing and functional cyborg hand! My son did this as part of a robotics course and this was one of his top favorite kits.

Think again abiut this purchase
Difficult to build. It sat for a few days because my son was very discouraged. When I helped I totally understood his feelings of frustration. Screws didn’t screw in correctly after straightening and straightening again. We finished the build but he was under impressed with all the work he had put into it.

Regret this purchase.
This was so disappointing and frustrating for our family. My very capable 9 year old had this high on his wishlist, and I absolutely regret getting it. We ended up throwing it away after 3 days of 2 adults and my son working on it for hours, and it never working.

Enjoying the cybord hand
We did it! If you follow the directions and take breaks as suggested, it can be done. My husband and I took turns with our 8 year old to put it together. My son loves it! All parts are working well!

Not a good toy for kids
Too heavy for the tiny screws that are supposed to hold it together. Broke right away. Did not have a true grip to really do anything with it other than open and close the hands before it broke from just falling onto the table a few inches. Very frail. Just bummed out. Bought it as a Christmas gift and took all that time to build it for it to not last very long.

My 9 year old did it all by himself over the course of 4 days. I only helped start a couple screws he struggled with and with the oil part. Otherwise, all him. So apparently he is gifted based on other reviews! Ha! Only giving 3 stars because a piece going into a tube broke after two days of playing. We are exchanging for a new one, so hopefully this was a fluke.

Worthless junk
Hard to put together, hydraulics are hard to with and piston levers are constantly popping out and are very hard to put back in. Was the only present my kids wanted from Santa and after hours of putting it together is essentially worthless junk.

Don't do it!
Way too hard for a 10 year old, whom is in gifted and talented classes. He's top of his fifth grade class, too. There is no way a 7 year old could do this. Dad stepped in to help and even he is frustrated. Do yourself and the recipient a favor and buy something else.

Bad. Waste of money
No way is this for a 7-10yr old. It took me, a 53yr old with a masters degree, 4hrs to get this together. Plus it’s a piece of junk. The rings where your fingers go pup off too easily. The super small screws were tough to screw in, my 9yr old could not get this done alone.
