Review on Optimized ROKR Wooden Mechanical Treasure Projects by Jerry Mills

Nice product! Assembly is not difficult if you follow the instructions carefully. The password part might seem a bit confusing at first, but once you get the hang of it (or just look at the last two pages), the rest isn't so bad. You have to be careful with some fragile parts, but there are extra parts for several wooden parts. I bought it for my mom as a mother's day gift and we ended up putting it together. We had so much fun and the end product was amazing! Definitely recommended for anyone who loves arts and crafts/DIY
