Retailer reviews
Summarized retailer review data when available.
I loved building this set and creating my first ever Dragons Rising set. The miniatures do not disappoint except for the fact that Raayu is tiny when he has actually grown in Season 3 part 2. I got this set for $22 AUD, which was pretty cheap for the quality of the mini figures and the type of set. Satisfying to put together, highly recommended
My grandson was very happy with his gift.
Ninjago Dragon Rising is a huge success. It's entertaining, dynamic, creative, and perfect for spending time with the family. We had a lot of fun putting it together, and it's easy because you put it together in order since each package comes with a number, making it simpler. I love this strategic and spectacular toy for children 7 and up, so they can develop their creativity and spend their time learning. It's worth every penny. It's perfect for collecting since it's high quality and long-lasting. Lego is one of my favorite toys for my kids.
This is such a fun toy. My little one LOVES Legos and had a lot of fun building this. My child, however, tends to focus heavily on making vehicles instead of creating action figures so that is exactly what he ended up doing. The perk of Legos is that you can be as creative as you want and this offered many unique pieces and colors to expand his creativity. Legos always get a 10/10.
Really fun set with lots of play options! The mech is poseable, the swords are huge, and swapping parts with other mechs makes it even cooler. My nephew loved this Lego. At 213 pieces, it's not too big but still feels like a solid build. It’s recommended for 7+.
Me and my daoughter love doing legos it’s super fun and it’s a challenge, it’s really entertaining and I always collect them so they can last for a long time .
My daughter absolutely loves the free sample of Legos Battle Mech that I received from Influenster. She loves assembling the pieces and then playing with them. They are very durable and provide hours of fun!
We are big Lego and Duplo fan and we totally love this Arin’s Spinjitzu Battle Mech set. The blocks and items came in little bags and the instruction booklet is so easy to follow with big pictures and illustrations. Our 2 years old love playing with the blocks, just stacking and taking them apart. We watch him closely during playtime to ensure he didn’t try to eat any. As adults, we had a fun time putting this together, very easy and quick. The end product is a robot that looks really cool on our shelf. Will definitely purchase other Lego sets and highly recommend this set. The details, the quality and design are all top notch and amazing.
LEGO Ninjago Nice colorful packaging, not too big. The playful images give you a good idea of what's inside the box. The instructions are clear, and you can finish it in about an hour. Ultimately, you have a kind of robot-like figure with the "good guy" and his helper inside. They look cute, and the "bad guy" also gets plenty of attention. Overall, a great LEGO set!
This was a gift from Influenster in exchange for my thoughts. I have given this 5 stars because of its living up to the LEGO brand. The character is very unique and vibes with a popular character of today’s younger generation. Building is fun and at the end you have a figurine to display on your shelf.
I received this LEGO set for free from Influenster in exchange for my honest opinion. It's a fun and compact set with a movable mech, an Arin minifigure, and a Baby Riyu figure. The building process is easy and fun, and thanks to the mix-&-match function, parts can be combined with other mechs. Ideal for young NINJAGO fans who enjoy creative play. Good quality. Super fun LEGO to play with!
My son loved this set! The mini figures were unique so he was very excited to have a couple new mini figs. The mech build was challenging enough that it kept him busy for a while but easy enough for him to do it alone. He loves yellow so the finished product will be staying on his shelf for a long time.
A fun LEGO set that is very cool to combine with the other Ninjago editions. Age 7+ but I built it with my four-year-old and it went very well! The Arin and Spectral Dragonian minifigures are very detailed. The dragon can also be placed on the arm of the robot. The shields for the knees that you can fold up are a bit strangely attached, with one clip and not in the middle, which makes them fall off quickly. Lego could easily do this with two clips (there is space for it) so that they stay better.
I’ve been building this slowly with my younger cousins as a fun activity and it keeps us busy. It’s a great set with a good amount of pieces and the finished product looks great. The instructions are easy to follow too
The LEGO Ninjago Arin’s Spinjitzu Battle Mech (71839) was an absolute blast to assemble. It took me about an hour to put together, and the process was smooth and enjoyable from start to finish. The mech looks fantastic once built, with great details and fun weapons. I really love the Ninjago line, and this set is a perfect addition to the collection. Highly recommend for fans of mechs or Ninjago!
This set was a big hit with my son. He loved building it and now spends hours creating battles and stories. The poseable mech and interchangeable parts with other sets make playtime more creative. The build holds together well, even after lots of play. Instructions were clear and easy enough for him to follow with little help. Pieces are typical LEGO quality—safe and sturdy, with no sharp edges. Overall, a great set for NINJAGO fans that keeps kids engaged long after the build is finished.
It’s a very nice Lego set. Wasn’t hard to assemble, came with with very clear instructions. My little brother enjoyed it and plays with it all the time.
My kids love putting together this Lego toy. The instructions and having the pieces separated out in numerical order made it easier. They felt that some parts were challenging, but it did keep them occupied for a couple of hours. This is great for kids who want to build on their motor skills and learn how to put together toys.
My son had a good time putting it together. The directions were easy to follow and he was able to do it relatively quickly. Would purchase this type again.
This was an awesome product! My son loved it. He was able to assemble it easily with the directions. He can make several things out of this one product. It came packaged well with all the pieces. It seems like it will last well
