"I bought this set for my sons fifth birthday after looking in my local Smyths shop. With all the similar sets that Lego produce this stood out, and it hasn't been a disappointment. My son managed to do around 90% of the build with me finding him the pieces and helping him along which was really enjoyable for us both. It took around four hours and the whole layout and design of the roller coaster is impressive. We have yet to build either of the alternative models but the set is worth it for the main build alone. Really impressed with it and my son absolutely loves it"
