My niece loved it. It’s really hard to find building projects for girls that are challenging. Wish they made more options for girls.

Amazing 👏

This box was exactly what we were looking for for our little 6 y/o tinker. The recommended age is over 8, but we took a chance and we’re not disappointed. With quality supplies, easy to follow instructions and a little help from mom or dad, the projects are ones our little boy is very proud of.

My 9 year old had a blast filming himself opening his box and putting all 3 of his robots together. He spent approximately 4 hours total on the projects, then over an hour playing with the robots and racing them across the kitchen.
He did need some help with some of the fidgetier steps but after several failed attempts at subscription boxes for screen free educational fun, I think we finally found the one that will hold his interest.

My 9 yo grandkids love building the different kits. The screws are tiny and difficult to work with, even for their father.

My son (7 almost 8), loves the Little Workboxes so far. He has received 2 boxes so far with 5 total projects. We have worked together to make 3 out of the 5 projects and all the projects have kept him intrigued and excited to see his project work. He is also excited that it is something we do together. I bought a 6 month subscription for him for Christmas.

Got a 3-month subscription for our almost 7-yr old daughter who loves to build, and she was ecstatic when she opened the first box! She got 3 simple robots to build, and HAD to build the crawl bot on the first night. She's trying to patiently space out building the others so she can share and show them to her best friend. Only minor issue we had was the quality of the double-sided tape provided - it wasn't strong enough for holding the battery pack to the body of the robot, so we improvised. She was definitely proud of herself after building the first robot and is excited to build the other robots and see what projects she gets in future boxes.

Best box for kids!
