I never out grew Lego. Jigsaw puzzles. Putting the Intrism Pro together was so much fun. I intentionally had to pace myself.
The instructions were good, not great, but good. You may need to really focus on the surrounding pieces on some of them. It was the depth perception on some of them that was tricky. Also the only video is outdated for the current version of the printed instructions. The step #s didnt align. Also not a big deal.
The pieces were all laser cut well. I didnt need the sandpaper as all. Also didnt have any broken wood pieces. One of the acrylic panels was broken on arrival, but Intrism send out a replacement.
I am sad that its together. I wish it were bigger, so it would take longer to put together. Now I move onto the excited of trying to solve the maze. I anticipate that taking some time, it seems tricky.
Love the product and would highly recommend to others.
