Bought as a gift, so I will not be putting it together, but it came quickly. We opened it and it looked well made.
I would recommend that you glue the outer box together all but the final piece. The box fell apart then I tried to solve the puzzle, and I lost the marble.
While the non engineering people enjoyed the challenged, our mechanical engineer laughed at others. Perfect way to entertain the entire family.
Your asking me for a review of a product intended as a gift for Christmas is a bit premature...seeing that it is only December 24th. Cool your jets...I'll get back to you after my grandson gets back to me.
I assembled this in an afternoon and thoroughly enjoyed it. To keep everything clean I wore vinyl exam gloves throughout, and did end up gluing several pieces that seemed a bit loose.
We loved the result so much we just ordered a second ‘pro’ to have a matched set!
Thanks for a great product at a good price.
Have looked at the instructions and plan to start building between Christmas and New Years. I am very impressed with the quality. The packaging is excellent and the product is very densely packed. Looking forward to starting.
