ROKR 3D Puzzles for Adults, Electric Model Kits Marble Spaceport LGC01, 472pcs Marble Run Brain Teaser Wooden Puzzles Building Toy, Desk Decor Creative Birthday Gifts for Men/Women 14+

I am putting this together with a 9 year old. They would not be able to do this on their own -- but we knew that going into the purchase. It's really fun to put together as a team -- they do what they can (which is quite a lot), while I do the fiddly bits like removing the delicate pieces from their mold, managing the teensy little washers that hold the axels together and quality assurance/troubleshooting for assemblies.Quality of the pieces is really high. Instructions are great. And so far, assemblies seem to work, and do what they do in really clever ways. Sometimes an assembly will feel flimsy, and then the next piece will add the missing rigidity. I feel like I'm in good hands with the designer of this toy.This is going to take you HOURS, btw. I'd say we're 8 hours and about halfway through the instructions. (And we're already talking about getting the kit that connects to this one for Christmas).Honestly, this is more than a kid can manage on their own, they would be frustrated. Kiwico and Crunch Labs have much better options for the youngers. But the joy of doing something that initially feels dauntingly hard and seeing it all come together into a beautiful, working object is something potent worth sharing, and this isn't something we would get out of a simpler toy.

This was my first wood puzzle kit that I have assembled. I was amazed at how precisely all the pieces assembled. The pieces were easy to remove from the boards, and for the most part easy to fit into place. I can tell you that I did not break even one piece of the puzzle during assembly. They do provide extra pieces of many smaller parts, just in case you need them. I did take the advice of other builders and work on top of a towel. Should you then drop a small piece it wouldn't bounce away. The other good advice is to sand all parts to smooth the edges. Also, use plenty of wax when instructed to do so. It seems like a small piece of wax that they give you, but it is plenty large enough to apply it liberally. The puzzle will have to sit level to work correctly. Once level, only small adjustments were made to have it working smoothly.It was a very enjoyable build. I am sure to purchase another!

I bought this as the companion set to Marble Night City that connects to make two sets into one. I thoroughly enjoyed building both sets and connecting the two. I’m continually impressed with ROKR’s build quality and engineering design with their sets. This makes the price worth it. The set was fun to build and I will buy other ROKR sets in the future. The combination of both sets makes it a great size for a table top conversation starter with constant movement of the marbles to catch anyone’s eye.

I got this for my birthday. It was a lot of fun to put together but it didn't hurt my fingers trying to get all the peices to fit and pop out of the molds without breaking them. I did build a few tools which was helpful but I didn't use one of them and I don't know why. I like that they gave extra of the smaller peices incase you lost them. Some of the peices seemed like they were going to break getting them out of the mold but I only broke one. The longer ones are the hardest. I like that the marbles go in many different ways but end up all at the end.

The media could not be loaded. This is a well-made product that is fun to assemble. All the pieces fit properly, and it actually works well as you can see in the video. Follow the directions closely and read all notations as far as part orientation and waxing.

I really enjoyed putting this together. It is very challenging, especially if you have large hands. I was extremely impressed with the quality of the small and very small parts. Take your time and follow those instructions. Just a few of the instructions are a little hard to understand.

Lots of fun to build.

The media could not be loaded. This is my seventh wooden puzzle, but the first that truly legit works - completely, without shimming, shaking, praying or tipping. All the routes work as designed. I was most excited for the automation as no matter how gently I turn the crank it pulls to the right putting the board of center. It worked perfectly and I realize some past issues may have been due to lack of speed and surely a lack of my experience. Each puzzle has been an improvement over the last, but THIS ONE ACTUALLY WORKS WORKS! Though I’ve done several brands, ROKR is my favorite for how the directions are laid out and the pieces marked. The tools are helpful but the wax, I don’t use the wax, I use Bert’s bees lip balm because it’s easier to spread but all the other tools are great. Have fun, I did!
