Thames & Kosmos Bionic Robotic Arm STEM Experiment Kit, Toy of The Year Finalist, Build a Mechanical Arm, No Batteries/Motors Required | Innovative System | Ages 10+ with Help, 14+ Independent Play

As grandparents, we scored big on this gift for our grandson. He enjoys the challenge, having risen above the challenge of even the most intricate Lego products. We will plan on buying similar items for a couple more years.

My son spent hours on this. Such a great use of time!

Bought as a present for 13 year old who found it interesting and liked it. He went wrong on one of the steps but he worked it out and carried on.Nice quality.

My 9 year old son got this for Christmas. Box suggests parental help at that age which is appropriate. He and I have been able to spend time building together

I'm excited to see my grandson expand his mind. These STEM kits are wonderful.

my grandson liked it very much

Great stem and idea but not easy to fit on even with adult help. Me and my boy manage to finish setting up but not working. We had our fun but I am lazy to dissemble to solve the problem.

Be prepared, this is not a quick build! It takes multiple sessions especially if you’re working with a younger kiddo who loses interest or doesn’t like to sit still. It took about 8 1 hour sessions with my 8 year old but it was well worth it! He had a blast doing it and once it is done it’s really cool to play with. All the parts are there and the instruction manual is VERY detailed with descriptions and pictures for every step. This helped a lot for my kid. The kit is very educational and definitely teaches them some skills. Good price too!
