We can’t wait for the next project!

My kids, nieces and nephews hardly ever interact with each other but building CircuitMess project brought the whole family closer. It was the most rewarding experience I’ve ever had with these wonderful kids.

five stars icon

I was able to get the children away from tablets.

My kids used to love Lego, but they’ve been glued to mobiles lately. I tried CircuitMess STEM kits, and all four are now enthusiastic. These sets are fantastic!

Futuristic and unique, love the Cyberpunk idea.

Super creative, futuristic and unique. Love the Cyberpunk idea, love the style. It’s our family hobby now.

Had the extra bit of swag stuff!

Got my James Webb Space Telescope today and everything look great. Came with all of the components and even had the extra bit of swag stuff they mentioned (stickers, bookmark, etc.)

Excellent subscription

My 9 year old gets so excited when a new box of Wacky Robots arrives. He sings all the way from the mailbox to home :). What a great way to introduce electronics and building to kids.

Stoked for Space-O project!

Words cannot describe how stoked I am for this Space-O project

I’m absolutely impressed with the quality of the Cyberpunk products.

Currently in the process of assembly. So far I’m absolutely impressed with the quality of the Cyberpunk products, packaging and additional educational reading. I’m not the best at soldering, but I’m improving as I go and am enjoying the process as well.

Worth every penny!

Great way to have fun, teach a kid and bond at the same time. My full support!

A great experience with my son

My son and I have assembled computers, race cars and many other things but the best experience has always come from CircuitMess. More specifically, together, we built the Ringo and the Spencer. And it was time well spent.
