"Very quick and easy build. Took me (mom) less than 2 minutes to build. My son loves the Super Mario sets, because they are interactive than regular legos. He absolutely loves that the instructions are via the iPad. I do as well, because I am not constantly keeping up with instruction booklets. The only update or change I would like to see is being able to see Mario on the iPad as he plays. It would be a great feature if he could match the iPad Mario land to his actual build. Then he could get a full visual in real-time. Otherwise, this is next level Lego everyone. The kids love it. Great job Lego Team!!"
