Review: Fun Project - Fun to operate - This was a fun project for my 13 year old grandson and me to work together. There were a few tough parts to assemble but it went together very well overall. The parts are laser cut and very precise. It is amazing how strong it is when assembled as there are no fasteners or glue used to hold it together. We had a small problem when finished as the marble run did not work as expected. We found that we had assembled one of the paddles backwards, and though this was a slight deviation it did make a difference. A little disassembly to correct this and it all works like it should. We did use a little glue to hold some of the raceways in place at an optimum angle, as they could shift slightly when moving the completed assembly. Once completed the operation is very mesmerizing as you operate the hand crank and watch the steel balls being moved around and operating various mechanisms along the way. Every now and then there is a glitch where a ball can jump the track. We found a dowel rod with a magnet glued on the end works well to pick up a ball that falls on the inside of the mechanism. There are assembly steps that have an exclamation point next to them indicating a critical step. It is important to ensure these steps are completed correctly to ensure the mechanism will work correctly. We spent 4 to 5 hours assembling and now there will be many hours of just playing with it.
Review: More fun than ships in a bottle - I received this as a gift. The fit and precision of the parts was astonishing! It takes significant finger strength to push the pieces together. Also a lot of manual dexterity to assemble the very small parts. The kit comes with sandpaper to help too tight pieces go together. I only sanded one piece as there was interference in the assembly otherwise. Very few errors in the instructions, and all were minor and easily resolved. The instructions were 3-D drawings like IKEA, only on steroids! I finished the assembly in about 12 hours and it worked! It was a little confusing that there were about 10 pieces left over. I went back through the instructions and concluded that these were spares. This would have been a fun thing to put on display at my office. Alas, I am 66 years old and retired. Still a 14-year-old at heart!

### ⭐⭐⭐⭐ A lot of fun but you need to pay attention and be patient
*by L***D on November 24, 2019*

This kit was an excellent start for me as far as building future wooden kits. Things may or may not work as promised in terms of the behavior of the steel marbles. But again very enjoyable to build and it taught me to be patient, take my time, look at the directions for proper orientation and such. I got introduced into the wonderful world of toothpicks that are much a staple in all of these kits and you have to be careful and strategic when using them.
