Lego is very creative

Originally posted on influenster.com

[This review was collected as part of a promotion.] 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.

Awesome

[This review was collected as part of a promotion.] 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.

Fun Ninjago Lego set!

Originally posted on influenster.com

[This review was collected as part of a promotion.] 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+.

Originally posted on influenster.com

[This review was collected as part of a promotion.] 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.

Originally posted on influenster.com

[This review was collected as part of a promotion.] 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.

Originally posted on influenster.com

[This review was collected as part of a promotion.] 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.

Great addition to the Ninjago line!

Originally posted on influenster.com

[This review was collected as part of a promotion.] 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!

Great fun for Ninjago fans

Originally posted on influenster.com

[This review was collected as part of a promotion.] 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.

Fun toy

Originally posted on influenster.com

[This review was collected as part of a promotion.] 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.
