I bought this for myself and put it together at work during a highly stressful time when I needed to take a break. The directions for this are very clear, and the pieces are well labeled. That said, there are a LOT of little tiny pieces. Even though I have very large hands, I was still able to work with the pieces carefully. Some pieces would fit together very snugly, but a number of rails were a loose fit and would easily fall off when bumped. This made parts of the assembly a little difficult (such as having four pieces connected to each other and trying to fit that group to the main assembly body while having loose pieces fall off). A little dab of glue will help to alleviate that issue, but be careful not to over do it. There were a couple of instructions that I did out of order as it made it easier to assemble, but for the most part the instructions are good. The tiny wax bar you have to use to wax the wooden gears was a pain to use on each gear tooth. I would have liked a better way to do that, perhaps if there was a wooden dowel to attach the wax to instead of trying to hold the bar itself between my fingers and hope to fit it between the gear teeth. Once done though, I received numerous comments about the piece and have had many people stop by my office just to see it run. Occasionally a marble will jump certain tracks, but over-all it's a great piece and was fun to put together.

Awesome! Took two days to assemble. A-17 is the hardest part for some reason to get to stay where it needs to and breaks easily, but glue will fix it. Make sure to pay really close attention to which direction everything should be facing during assembly and work slowly. My kids really enjoy playing with it!

RoWood Marble Run 3D Wooden Puzzle I think is worth the cost. I looked at other 3D mechanical puzzles. Even ones rated very high had various problems. Those puzzles were not terrible but I wanted to have a completed project that worked well. I did have a problem at the end. One ball lift gear would not work correctly. All I did was go back to the instructions and review the steps for that part of the project carefully. I found the problem and made the fix. Now the machine works great! I had a good time putting it together. I assembled it over a few weeks in between other things. The instructions were very complete. Be careful to look at ALL instructions and not make assumptions on the assembly. The parts released from the wood/plastic boards easily. A few required a little help from a utility knife. Overall I am happy with the Marble Run.

This is a very well designed set of good quality. However, putting it together is quite difficult and it is well nigh impossible without breaking some pieces during assembly. So, have super glue handy! I had to make a few adjustments to the tracks to get the balls to travel the way they are supposed to. But now it works beautifully and I play with it all the time. It looks lovely and is well worth the price. Just be VERY PATIENT and have a hobby shop at your disposal.

This kit is amazing. When we first opened it I noticed the precision with which each piece was cut and how easily they pop out of the sheets. The instructions were clear and easy to follow and working on it as a family project we spent a few days getting it done a little at a time. It amazed me to see how smoothly the gears thurn and effortlessly carry the marbles back to the top. Some care needs to be given to not snap small parts but we made it to the end without incident. Now this is an amusing piece to have around and remember the time spent enjoying puting it together as a family. Definitely recommend.

I just found the pieces to be too fragile. Included are a number of replacement parts, specifically for the type of problem I encountered, but not enough of B23, one of the most used parts. There is a significant amount of trill and error in figuring out how things are supposed to go together and that's part of the fun of putting it together. However, the act of placing and removing items weakens them. The companies website allows the ordering of additional replacement parts. A Google photo of the broken or missing part is required from the manual. The form never has accepted a picture so I have been unable to submit the form. So I have the item 90% completed but can't finish it because of broken parts. I much prefer this type of activity to putting together a jigsaw puzzle although there are similarities. Having a working fun machine at the end is what enticed me so I'm a little bummed that I'm stuck.

I'm impressed. I dont often right reviews or do videos but I have to give this make credit for an outstanding design. I had low expectations and hadn't built anything like this before and just figured that it would be sloppy and junky because it's wood. Putting it together I came to admire how much detail it takes to design a kit like this so I have to applaud them ROKR! Sure there are delicate parts and that's part of the fun of a kit. The instructions were easy to follow and it was a super fun experience with the kids. I agree with the 14+ by the way it takes good finger dexterity and strength.

Can I just tell you that woodworking tinkers, namely boomer dads, really love these things? I can get any put-it-together marble run, of any stripe and design, and my pops will be as happy as a pig in a mud. You can't go wrong with this one. Pretty cool and mesmerizing. Excellent gift for the adults who love model building. The comment is that it "is like Legos for adults." I have the sense he's going to discover that adults like Legos just fine, and then we'll REALLY have a problem. Definitely loved to see him happy with this one!

Lazer cutting of parts is very precise, everything fit together and functioned perfectly. Hours of fun building and using. I have purchased other kits from this company and am sure I will buy more

In places very fiddly and easy breaks. Would not purchase again.

Sehr anspruchsvoll an Fingerfertigkeit und Deutung der Anleitung.

Alles bestens erklärt und genügend Ersatzteile dabei. Würde diesen Bausatz jederzeit wieder kaufen. Auch der Laserschnitt ist sehr präzise, sodass man nicht nacharbeiten muss. Ein einziges Teil musste ich mir zusammenschustern, da dort genau ein kleiner Ast war. Man muss bedenken, es ist Holz und Holz hat nun mal Äste oder etwaige „Fehler“ im Material.

Product came as described. My fat fingers were able to assemble it pretty well. I broke one piece that needed glue to fix, and just plain could get one other spacer piece to fit, but the thing works well once it's assembled. It's going to be a great "desk distraction" in the office. Take your time, read ahead in the instructions, and make darn sure that you fit things together tightly before moving to the next step. My biggest headaches came when fitting pieces onto the board near the end, when I didn't take the time to fully press everything in.
