Retailer reviews
Summarized retailer review data when available.
I gave a LEGO Ninjago set as a gift to a 5-year-old boy. He was extremely enthusiastic when he received this set.
Great birthday gift
Nice material and very easy to build for this age group.
The mech is really very bad in terms of design, but the vehicle that the anacondrai warrior can ride in is actually okay, but overall it's a rubbish set. And in the show, Jay does NOT wear a mask in this scene, but in this set he does.
