This is a super cool lego set. Easy to pose, lots of playability, and just looks awesome. Comes with a good number of minifigs, all with some neat weapons and armor. I particularly like that there are a few exposed studs on the mech's arms and behind its head where you can place some of the minifigs - either attacking or riding on the mech. My kids and I love it, buy it!

I bought the fire and stone mech to display in my city on top of buildings but the lack of not having any knee joint at all makes posing it the way I want impossible. It is a great looking set and fun to build. I wish I knew there was no knee joints I would have past on this set. For kids it is perfect

It was the most involving lego project for my 9yo son. He has spent two days building it, without any help. And now he keeps playing with that almost every day. The set is awesome. The set includes Fire Stone Mech and 5(!) minifigures. The most impressive thing is that you can place figures inside the mech's chest.

This toy was a hit with my son and his cousin. They just love building things. The completed action figure is very cool looking. It took them a few hours to put it together. I like these types of toys because it helps them to work together. I feel like they are learning building skills which will help them later in life. It takes them away from electronics and let's them use their thinking skills.
This building block set is a beast, in a good way! My two sons, ages 13 and 8, have built many Lego sets and this was by far the most entertaining and longest project for them to build. I sat near them to watch how they placed all of the bags in order and eagerly read the instruction booklet, well my 13 year old that is. My 8 year old put the ninja figurines together and immediately started to play while my 13 year old did all of the hard work, as usual. It was a lazy afternoon and into the evening during our self imposed quarantine when they finally finished the set. As usual, there were extra pieces included.My oldest said there are cool features within the Fire Stone Mech that he wasn't expecting, like the storage area under the shoulder guards and how it can ... MoreThis building block set is a beast, in a good way!

And with the current situation that encourages people to stay home more often, I highly recommend this set to pass the time. My boys have already spent countless hours role playing together with this set despite their 5 year age gap. It's a very cool set indeed!
This LEGO Ninjago is one of my favorite lego piece I have. The samurai is so big and has so many amazing features. The box came with 5 figures all have weapons and some also have shields. All of the pieces for the people can be exchanged and mixed up like normal. The set also comes with a sword in a stone type of item with green fire so they can battle over the sword. The giant Samurai is so cool. You can put one of the figures in his chest. He also has really big swords and a cool feature that shoots out LEGO like pieces! The set comes with 968pcs. If you haven’t bought this Set go get it I highly recommend It!!!
My grandson really wanted this toy. It was on his Christmas list. So at the minute it is an unopened present. So can't tell you much about it apart from that he'll be really excited to receive this on Christmas day.
This Lego set belongs to my five year old brother, but I helped him build it. There were quite a few new pieces such as the 2x2 curved bow plates, in red and light grey, and the ridged brick. A new colour is a 6x6x2 cockpit in transparent orange. The finished set is quite large, and has enough space in the cockpit to seat two of the five minifigures in the set. The bottom of the mech’s feet have rocket boosters on them. The five minifigures in the set are Hero Kai, Hero Cole, Hero Nya, and the two bad guy’s, Moe and Murt. Overall, the set was really good.

My son was so thrilled to have received this for his birthday! The smile lingered on his face upon opening his gift. This was the most difficult lego he has assembled so far and kept him busy for days. He was done in less than a week! Each day he would show me how far he has gone in building it. He was so amazed on how the joints are so articulated and can stand in its own. It was worth the money paid for. I just helped him place the stickers as he wanted it perfectly done. He wanted his robot to be included in his collection. He was so proud and happy with it. I am so happy I bought this. You can never go wrong with lego purchases.
Let me start by stating that I am not a true Ninjago fan but do enjoy building the sets. This one was no different. It took a little longer than I anticipated but that could be a good thing (not an easy build). I really like the new design that enables the swords to be held in the hands without needing to be connected. There were not many 1x1 pieces which made the build go faster. The end result resembled the photo no the box exactly. I look forward to the next set.
