Review: Fun and creative STEM toy for kids - This set has kept my kids entertained for hours. The gears snap together well and allow for a lot of creativity — from simple builds to more complex moving designs. It’s a fun way for them to explore STEM concepts while practicing fine motor skills. Some of the smaller gears can be a little tricky for younger kids to snap in, but overall it’s durable, colorful, and makes a fantastic gift.
Review: This thing is awesome! - Was a Christmas present to my 5 year old son. Since opening is presents this is the only thing that he has played with and he got a ton of presents I'm seriously telling you. He loves this thing and you know what even as an adult you get into it it's fun. Creating different things different levels you can have the chain you don't have to have a chain he loves it and he spent lots of hours on it already! Super easy to use. If you have super small kids some of these pieces are chokable. Thankfully my son is bigger than that and I only have one.
