"I was slightly sceptical at first with the hidden side line, however my son (7) saw this set online and put it on his Christmas list. I felt it was reasonably priced and I expected a fairly simple, steady build... how wrong I was! This set is so challenging, I have many modular sets, ninjago city/docks and it definitely competes in the same league. We had so much fun building this, the hidden extras of the school transforming into a monster are fantastic, the designer/s are super clever to come up with these features. There’s no ‘empty’ areas, it looks great normal and transformed... In my own opinion I can honestly say this is one of my favourite sets of all time. That was just the build, the app is also brilliant. We haven’t played on the app very much as we prefer using our own imagination but it’s a feature which I can imagine will advance in the near future. Overall 10/10, I’ve since bought 4 other hidden side sets which I will review separately but if you are sceptical then be reassured that you will not be disappointed in Newbury high school"
