### ⭐⭐⭐⭐⭐ Great toy for a nice range of ages, great customer service
*by C***E on May 9, 2025*

The science kit arrived, and my 3 and 5 year-old absolutely love it. They played with it a bit hard, and a two pieces broke quickly. I decided to award 5 stars for three reasons: 1. Customer service was fantastic. I reached out via email, received a quick response, and after sending video of the issue they sent me replacements right away. 2. The ease and intuitive nature of this toy. There many aspects that are fun for both my 3 year-old and my 5 year-old, and enough sophistication that they'll continue to keep interest for a while. 3. The instructions and explanations are great, and this kit has a nice range of activities that are fun. My only negative would be that a few pieces broke quickly, but they were also replaced. Overall, highly recommend!
