Fun and a good challenge!

Very cool! Takes some problem solving to assemble. My niece got a little impatient and broke one of the pieces but we glued it and it still works.

Two of the pieces broke as I was putting it together, but fortunately I had some wood glue on hand. The chain kit did not move at all the first time I put it together, so had to take it apart, sand some pieces, wax them and put it back together. This required a decent amount of time and alot of patience, but now that it is done, I'm excited to show my 9 yr old grandson. When he gets a little older I will probably get another set for him to put together himself.

Looks great when finished easy to put together. Not completely workable as some parts do not line up but still works overall really good though

Came as described

No written instructions. Pieces do not easily fit together. Some pieces broke while removing.

Fabulous puzzle

This was my first wooden puzzle I've put together, and definitely won't be my last. I chose the marble run because my 3 year old son loves them and he enjoys "building" with me (which mostly means watching and asking of it's ready yet). As my first puzzle, this was very engaging to put together and the instructions were clear for me as a beginner to understand easily. Luckily they put a few spare of the smaller pieces as one of them broke and my son lost a few. We started one morning, worked on it here and there throughout the day, then finished it the next morning. I could have finished faster alone, but half the fun is letting my son see all the parts come together and explain how things work. The end result looked exactly the same as the picture, and the hand cranked worked as it should. Very satisfied and very excited to get another one!!
