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.

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

Sehr anspruchsvoll an Fingerfertigkeit und Deutung der Anleitung.

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.

Fun to put together. I have never put a puzzle or model together before so it took some time to put together. Finished in about 10 hours. Had 3 pieces left over that were not mentioned in the instruction book, however it didn't seem to matter, with the finished project. only a few pieces were hard to put together, otherwise (with the help of u-tube ) they finally found their home.
