We purchased these for our 4-5 yr old church classroom and the kids (and teachers) LOVE them. It encourages creativity and teamwork as the kids build together. It's great for boys and girls both!
We received this as a gift and I think I love it as much as my son. I wasn't sure at first what to think of it but as soon as we set some up and starting turning the crank, we were both hooked. It is mesmerizing to watch and create. We are excited to build on with other kits, too! But, clicking the base pieces together is a little bit challenging and holding the base still while turning the crank can be tough. It's hard to not touch gears while holding the base steady, so you can end up stopping the whole thing from working. I'm sure as kids are older, they can solve the problem. But my 3.5 year old has me hold it down while he cranks the handle at full speed to his total delight.
