This is a very good product. I use it for STEAM in the classroom and I'm sorry that I didn't buy the other options as well. My students loved them. It's a very educational kit and the models are easy to assemble and comes with instructions. Unfortunately, there were no batteries and the pieces of wood could have been a little more sturdy but it comes with glue if you want to make the models permanently affixed. These kits will make great gifts for children who love science/engineering or event of you're trying to introduce it in a fun way.

We have only done one of the projects. Got it during Black Friday. Parts are good. My 9 yr old did need some help in holding down things to screw parts. But overall it was super fun. Great gift for 8-11yrs old if they are into STEM education. There are Times when the gears are overlapping or gets stuck. Still worth it I feel. Also keeps kids away from screen.

Got this kit for my eight-year-old son and it was a big hit. He needed some adult guidance to complete the construction, only with the tiny screws going in straight. The directions were a little tricky to follow because they were made in a different language originally, and some of the translation didn’t make sense. But it didn’t take us very long to build all of the kits and they are a lot of fun to play with. Highly recommend getting this if you have a kid interested in stem.

My son loved putting these together. They were easy enough for him to do independently, they were not very difficult though, he is 12 now and they were good for him up until about 10 years old. He still had fun. They came with even the screwdrivers to put them together

8 yr old had some trouble assembling these structures, especially the tubes on the digger and the wires on the elevator. Some of the wood pieces cracked when the screws were tightened.

My niece love it

We bought the 5 STEM building set with the elevator, telegraph, newtons cradle, hydraulic excavator, and sun earth moon model. Here is our review of the elevator: The long slim pieces of wood are easy to break, so kids may need help screwing them in. The elevator worked just fine EXCEPT that it makes a noise sometimes instead of moving when you push the button.... we fiddle with it and it works again, but the issue is confusing to us. Here is our review of the Sun, Earth, and Moon model: Coloring the 3 balls is difficult because the marker comes off on your fingers and does not seem to want to stay on them. The motor keeps falling down because it is not screwed in place. The battery pack is not accessible to change batteries if you stick it down in place so keep it removable - don't use the sticker. It worked perfectly when in motion - no issues. We lost the planet balls quickly which is disappointing. Newton's cradle was wobbly and did not function well. I think it takes a lot of skill to get it set up properly. The telegraph machine's lights never worked but we were able to transmit sounds. The 8 year old took the hydraulic excavator home and I have yet to see it functioning... not sure if it worked given the silence on it.

Our 5th grade grandson found this kit to be easy to use and enjoyed making the items.
