Amazing set
The mech looks absolutely great I love all the details on it. the cape is an amazing touch I love how even though we have so many mechs this still feels like something new . the figures are alright too kai's suit is amazing . the scene depicted with the fisherman falling off the boat and the tentacle being is absolutely amazing and great to display.

Overpriced, yet worth every penny?
This set brought forth a great building experience, great for display, and play, 10/10 would buy another if it wasnt so expensive

Missing Parts
I had started building this set, but the third bag was missing pieces. I couldn't complete the left leg and now have to wait for replacement parts.

Oh no! If you can't find the missing pieces, reach out to our awesome helpers at LEGO.build/Service-BV and they'll see if we can get those replaced.

One of Ninjago's best products yet!
The Fire Knight Mech, while small in terms of minifigures, makes up for it in it's uniquely designed mech and sea monster. As a diorama/display piece, this knocks it out of the park. As an adult Ninjago fan, it is an absolute must have.

Recommend
[This review was collected as part of a promotion.] It was a challenging for younger Lego fans. But will be fun if we build together. As is usual with Lego, the instructions are clear, there were no missing pieces and the quality was superb. Highly recommended.

The best Ninjago set
[This review was collected as part of a promotion.] It's really awesome and so fun to put together! I think is the best Ninjago yet! Also it's HUGE. I absolutely love it and so glad I got to experience it, I never would have thought of purchasing a Ninjago set but excited to state I was wrong.

Very Detailed
[This review was collected as part of a promotion.] Wow, this is a very detailed Lego set! Lots of pieces. It isn’t super difficult to do, but it does have some smaller details that require concentrating. Turned out amazing and was a great activity to do!

Amazing Mech!!
[This review was collected as part of a promotion.] This Lego Fire Knight Mech set is AMAZING! The packaging has a really special feel to it with being from the legends series. The set comes with everything you need to build this awesome mech. My teenager loved building it and is proud to display the set. Great value for the money.

Best of Ninjago Lego
[This review was collected as part of a promotion.] Firstly thank you Lego, for letting me try this for my honest opinion. My son was ecstatic when we opened the package. His eyes had a shine when we saw the fire knight mech suit get complete. We are a lego family and have over 100+ sets with across various lego themes. Ninjago is very close to the heart as it's truly a Lego theme and has a vast presence across media platforms. This lego mech suit, bring that feel of Ninjago legends in your hands. The build instructions are clear. The exclusive poster is very cool and is a welcome addition. I would love to see more mech suits get added to this series. Must buy.

Lego- Build memories, build fun!
[This review was collected as part of a promotion.] The Lego Ninjago De vuurriddermecha was awesome to build. It's a 996 PC set. Lego does it again. They make it highly detailed plus fun to build. The mech is detachable from the base plate scenery and can be used with other sets. My son had a blast building this and he started playing with it as soon as it was built. Highly recommend Lego for some quality bonding time.

Worth ever penny
This build is beautiful and my boyfriend loved it. The box is a beautiful price of artwork. My boyfriend enjoyed the build and say it was easy and even bought the companion build Ninjago Dragons Rising Cole’s Titan Dragon Mech 71821. He said the build was enjoyable and not complicated. The build was worth every penny and is a definite collectors item. He hopes to see more from Lego in this line to continue the collection.
