Great toy for a nice range of ages, great customer service
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!

My son’s favorite educational game!
I bought it as a gift for my son, the children are simply delighted, no one will pass by. The scientific set for children is very interesting and multifunctional, even girls like this set, it is very easy to use, the child will play with pleasure. I think it is very useful, as it helps boys develop correctly. My 3-year-old son copes with it without problems and understands the pros and cons well, although I bought it for a 7-year-old child. It has a steam function module, different types of spinners, a 3-color lamp, a vacuum cleaner module with a ball, a module with an indicator of current strength, and most of all I liked the glowing cord. I can call it the best toy for a boy! It is affordable and meets expectations. The cords are very easy and simple to connect. It is made very well, all the cords are enough to connect the entire system and there are many spare parts, which is very pleasing. The set includes a good instruction manual, which has more than 400 projects, it helped us quickly and well understand and play. The package size is average, the set is lightweight.

Broken part after 3 months. Can not find replacement.
I brought two on these for grandchildren (4 yr old boy and 3 yr old girl) for Christmas 2024. It is March 2025 and the knob control is broken. Trying to find a replacement but you must purchase the entire product. On the whole, the children love it – my granddaughter is thrilled by it. It is very entertaining and they have become interested in circuitry. I recommend it. Also, I wish they sold individual items to expand the system rather I can’t find any – you have to buy the entire set which becomes redundant.

Great learning toy and great customer service
My 2.5 year old loves this game. He plays with it almost every day and makes a new circuit each time.The company was also wonderful and very quick to respond when one of our pieces didn’t work and sent over a replacement.

Perfect set for my 8 year old.
My 8 year old loves this set and doesn’t like to put it away. It is constructed well and it is well labeled so my daughter can create new designs all on her own.

I bought this STEM science kit for my 6-year-old grandson, and it was a total hit! The experiments are easy to follow, super engaging, and packed with hands-on fun. He was so excited to wear the little goggles and play “scientist” while learning real science concepts. I love that it encourages curiosity, problem-solving, and creativity—all while keeping him off screens. Everything was well-packaged, safe, and age-appropriate. It’s a great bonding activity too! Highly recommended for any curious young mind.

Fun, educational, well-designed with clear instructions easy for kids to follow. However, not good value for price.

This was a big hit! My son loves this circuit kit. The first two weeks he played with it non stop and just had to bring it to Nana’s house. We’ve had it now for almost a year and he still plays with it. When he pulls it out, he stays engaged for almost an hour. He’s almost 6 years old and tends to have trouble sitting still and focusing for long periods. I highly recommend this product.
