Reviews Summary
Customers say these monthly engineering kits are exciting and engaging, with children eagerly awaiting each box's arrival. The builds are well-designed and durable, typically taking 30 minutes to an hour to complete independently. Kids enjoy the hands-on learning experience and continue playing with their creations long after building. Many mention the educational videos that explain engineering principles in accessible ways. Parents appreciate how the kits encourage problem-solving skills and inspire interest in engineering. The subscription works well for various ages, with some younger children needing minimal adult guidance. Customer service receives praise for quick responses and free replacement parts when needed.

    My son gave up video games and devices.

    Yes CruchLabs gets a five star from this Mama. My kids receive build box for my son and my daughter creative box. They play and create and figure out how their next movie or project or experiment is going to plan out. Goodbye video games and devices. When I go to the store if they ask for a toy I remind them about CruchLabs and they rather have these boxes. Don't even throw fits at the store anymore. We love Gus ❤️ Rick ❤️ Marty and Frank ❤️

    We are thankful for CruchLabs team and families that put in the hard work into making these affordable and learning fun. These fit into our homeschool life. God bless you all. Can't wait for the book serious.

    Crunch Labs Build A Box Review

    The CrunchLabs Build Box is a monthly STEM subscription service designed for children ages 8–12 that focuses on hands-on engineering. Each kit includes all materials needed to build a functional toy that demonstrates a specific "engineering superpower," such as flywheels or ratchet mechanics. It is amazing and I would definitely recommend for anyone!

    Awesome experience

    My daughter was so excited to get a crunch labs build box for her 7th birthday! She absolutely loved the video and putting together her first build. It was amazing to watch her do it all on her own. She wants to be just like Mark when she grows up and I love her enthusiasm for it!
