"Well I must say I haven't enjoyed the experience of model building years but this did the trick! The crane was a pleasure to build, its pretty big however, and takes a fair amount of time to assemble. I got this as a gift for fathers day because my kids had caught me looking at it several times at toys r us LOL. The instructions were very well written and don't let the rigging scare you, the instructions guide you through effortlessly. Everything functions very well as expected. I will definitely be getting more technic kits, I only wish I had gotten the mobile crane II before they quit making it :("
