Incredible

This set is absolutely awesome, I love these mechs and most others from ninjago. I only had one issue there was a missing piece, a light gray bar tile, I had to change it to a regular tile piece. Other than the missing piece this is a lovely set that I would definitely recommend.

Amazing LEGO set

[This review was collected as part of a promotion.] This Lego set is amazing! The NINJAGO twin titan mechs action figures were so much fun to build with my boy. Each titan comes with its own bags with Lego pieces and books with easy and straightforward instructions to follow. We had so much fun building these and using them for roleplay. They come with 3 mini figures that can be placed in the titans . Both figures have movable features which my boy really enjoyed exploring and putting them in different poses to recreate a fight . There's a stand to build too and you can attach one of the figures to it to create midair poses . I was really surprised to see how big the twin titan figures are . They are much bigger than we expected! My boy has been playing with them since we received them and they are holding alright. This set would be an amazing gift for any LEGO fat !

loved building them

[This review was collected as part of a promotion.] I really enjoyed building these, instructions were easy to follow and explained really well. They have moveable joints in legs and arms. So many poses you can put them in. I highly recommend these. I am a beginner with lego and I built them with no problem at all.

Amazing set

Some of the best ninjago mechs so far. The build is very satisfying. And they look great on shelves. I would have loved to get full figures for jin and mira instead of only their heads

The last 2 mechs are Still Great!

I'm a big Ninjago Collector and I love the titan mech series. So these mechs & this set, was always a priority and a want for me. To answer the big question: Are these good Titan mechs? Yes. They are! Are they the best? I'd say not quite. I think where these mechs shine the most is with the build experience. For mechs that come together in a box, they feel very distinct from each other. The posability of the mechs is good I'd say. While not to the level of Coles titan mech, they have ankles, legs, knees, wrists, fingers, head, arms, hand and waist movement which is great. They are a good size, especially in hand they feel very good. The figures are alright. Both kai and nya have cool new suits I enjoy, and the ability to switch the heads to Jin & Mira (new ninjas) is a great inclusion. If they're are any downsides, if say the fact there is only 1 stand you can fit 1 Mech on isn't great. I'd love to pose both at the same time but oh well. And I wish the Oni warrior had a little turret or canon to use against the mechs. Overall it's a good set for mech fans and it's a great way to complete the line. Not the best mechs, but still great mechs

Thanks for letting us know how much fun you had building the NINJAGO® Titan Mech set. It’s awesome to hear it earned a top spot in your collection and that the unique builds and posability really stood out to you—true ninja engineering at work! We’re sorry it’s not quite how you’d like it, especially when it comes to displaying both mechs at once and the Oni warrior’s gear, but your feedback will help us make improvements in future sets.

Great

[This review was collected as part of a promotion.] Hard to build, but enjoyed making it. Instructions are very clear and liked the step by step guid. Each model is light weight which is good. As always its lego so standard amount of noise made when tipping out and solid bricks
