Review on ROBOTIME 3D Wooden Puzzle Mechanical Gear Clock Owl Model Kit For Teens & Adults - DIY Building Set by Dave Goodman

I think its funny that one of the features the review asks you to rate is "easy to assemble". I purchased this because it is precisely not easy to assemble, but is very challenging. I enjoyed every second of it! I put it together a little at a time and it took about a week. I didn't want to try all at one time because I wanted to enjoy it and take my time. I tasked my 5-year old with helping me find and hand me certain pieces, although in general this is definitely not suitable for a child. Parents need to have fun too though!
