On a recent holiday trip with family, I came across this shop in the mall and lo and behold, I'd made up my mind on getting my hands on my first LEGO set. Growing up, I'd played with similar brick sets and block sets, but I'd never had a LEGO set before. I found this to be a great first LEGO set and would highly recommend it to anyone who is looking to get their first ones, or to add to their collection. I've made all the models that are featured with this set, and some more of my own. Pure fun! And they really help me to think and take a break and just rewind and often bring back great memories! This is a great gift set to give to a young kid to make a special day even more special! Thumbs up! Can't wait to get my hands on more LEGO sets!
