Great package for the price and my boys loved it. Different ages and all enjoyed. Some more difficult than others but all enjoyable! Educationally appeasing. Quality was good, as expected. Small pieces, and small builds but nice.

Perfect kit! Instructions were easy. My grandson loved them. We especially liked the solar panel car.

Such a great value. Fun to assembly and play with. Great for 8-14 year olds.

Bought for 7 YO great grandson for Christmas. He was extremely when he opened it. It appeared to have lots of small pieces but made quality material.

It is fun for children to put together and enjoy it!

This was easy to put together until my student tried to put the white gear on the motor shaft for the solar car. The shaft hole on the gear was too small to fit on the shaft. I ordered another kit thinking it was just a mistaken part included. The new kit had the same problem! Anyone else have this issue?

Great learning tool for my 10 year old grandson. He can almost assemble them by himself. This is a quality product.

My 5-year old had a lot of fun with this kit! It has supplies to build 4 projects: a solar powered car, a wind powered car, an airplane, and a pair of binoculars. Even with my lack of assembly skills, I was able to help put these together with no frustration. My only word of caution is that some of the wood pieces are fragile and will break if you apply too much pressure when snapping them into place. Overall, worth the cost. The binoculars really work and the wind powered car is great!

After purchasing, then returning a plastic solar-powered robot of a similar design (despite hundreds of positive reviews), I decided to try this one. The quality is very good and significantly better than most of the ‘7-in-1’ or ‘14-in-1’ plastic versions available. I purchased it for my 5yo knowing it was too advanced for him to build but that he wanted to do it together. A 10yo could do it themself. The wooden pieces are laser-cut and perfectly fit together. Directions are easy to follow and clear. So far we’ve built the wind-powered car and solar-powered car and both work great. The parts, and overall finished products, are good quality and will last if properly cared for. All up, much happier with this slightly more expensive wooden option compared to the plastic versions which are pretty cheap and poorly designed.
