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 boyfriend is a whiz at puzzles, every year for his bday I try to find an impossible puzzle. Ten years I've been trying and this one finally challenged him. He completed it in one sitting on a rainy day (like 6 hrs) with movies playing in the background, but even he said it was hard. I can't imagine a kid could complete this without help. I'm pretty sure we'll take it to the goodwill, as the toy itself isn't all that entertaining for a 40 something man, but I was giddy that I finally challenged him. Absolutely would buy something like this again!

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

my grandson liked it very much

He beggggggged us for this. It was his big present for 10th bday. We opened it, he took one look at it, and said “dad you build it.” We tried to get him to do it with us, but he didn’t want to help.Once built (it took my husband a considerable amount of effort), my son has played with it once, briefly. The grabber arm has limited functionality. The alternate version, the worm, is cool but it only does so much.I’ll probably find a place to display it because it looks neat at least. But I will not buy another building toy from this brand.

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!
