Join a thriving community of makers who are developing real-world skills, exploring new technologies, and building amazing projects with CircuitMess. Read what they have to say about their experience:
「Incredible products and an amazing learning experience」
「I’ve purchased several products from CircuitMess, and they’ve all been exceptional. The instructions are clear, and the experience is unmatched. I highly recommend ByteBoi and Wheelson—their interactivity is incredible, and it’s truly mind-blowing to see what you can build with your own two hands.」
「The perfect alternative to screen time」
「After a long day at work, I used to just zone out in front of the TV or scroll on my phone for hours. CircuitMess completely changed that. Now I spend my evenings building something cool and meaningful. It’s fun, super engaging, and way more satisfying than wasting time on your phone.」
「A fun way to set kids up for future success」
「I got the Wacky Robots kit for my kids, and I couldn’t be happier with the results. They’re having so much fun building and experimenting, but what really amazes me is how much they’re learning. These kits are teaching them real life skills, things that will help them in school and, down the line, help them in their careers.」
「Brilliant STEM kits for kids」
「We have recently bought the CircuitMess Bit along with 9 different mini robots to replace another known STEM brand. The difference is night and day. CircuitMess provides fun projects for kids to actually enjoy.」
「Unwind and create after a long day」
「After long, stressful days at work, I was looking for something that could help me unwind and disconnect from the constant screen time. Building and creating something tangible is relaxing and satisfying. Highly recommend it for anyone seeking a stress-free, creative escape.」
