  • Cutting pliers are a must
Cutting pieces out with scissors is a torture even for adults. Cutting pliers make the process enjoyable, even for kids.

  • 9 yr old loves it
This is a big step up from legos. Engaged my grandson to think about how things went together and then see the function of his work. More than a toy.

  • Such an exciting gift!
I ordered this for my son’s 9th birthday, after he saw it online and became immediately obsessed. He couldn’t wait to start building, and I had to stop him from ripping it open multiple times. This definitely required close parental involvement (for his age, at least)…he didn’t appreciate the value of the directions until he used the wrong size screw in an early step, and we had to undo several pieces. After that, he was VERY careful to read the guide (which was the best instruction set I’ve ever used - clean / easy to understand drawings), and he carefully filed off the little plastic nubs from each part after we snapped them out. The pieces are plastic, but we didn’t have any just break on us…but be warned, some pieces can’t be unsnapped after they are clicked together (this isn’t a project you can make multiple times). At one point when we were almost done, my son accidentally clicked two pieces together without placing them around a third piece…and they wouldn’t come undone. I tried to pry them apart with a little screwdriver, but I snapped off one of the tabs. He felt awful and cried, but thankfully we could fix that with superglue. We also had one piece with a manufacturing defect, but I reached out to the company, and they kindly sent us a replacement. I think it took 5 hours over 2 days to assemble, but it was worth it. I’ll re-emphasize: parental/adult involvement is necessary…don’t turn a younger kid loose with this project. We bought another one for my son’s best friend, but I think he worked on it alone, got frustrated, and put it away…hoping he didn’t snap together pieces that can’t be undone, because that will make the set worthless. Our experience was positive, though, and now my son is scouring the company’s catalogue to choose his next project, which he desperately hoping comes under the Christmas tree. ... show more

  • Great project
My oldest son (15) bought this and enjoyed putting it together. It works and is fun to show to people.

  • Great project!
We love these products we just bought the arm as well. My son needed a few extra parts and they were sent for free by sending their customer support email. We are so happy with this purchase and will continue buying from this brand!

  • Robot hand
For 10 year old. He loved building it and then playing with it but that lasted about a week. Prefer to go with a drawing set or science kit that would last longer 🤔
