"This is probably the worst Ninjago set I've ever purchased. It's a very weak build and the minifigures don't justify the price. I got it for $30 at Target, which is $10 cheaper than it's retail, and I still feel like I paid too much.
The problem is that the set is just a gimmick for the ninja spinners. That in itself is fine. There are other sets that have incorporated the spinning gimmick, but have still been an excellent build. The best example I can give you of that is the Ronin R.E.X. set
The entire set is built around the idea that you have your spinjitzu ninja "duel" with a spinning saw blade
The end result is that the S.O.G HQ set will take up way too much space on the shelf, but will look very sparse and uninteresting.
There are only two pluses I will give to this set. 1. It comes with a different kind of bike. and 2. It comes with "Snake Jaguar" Zane...and he is exclusive to this set. But those alone doesn't justify the purchasing this set.
Nothing else here is special. Not even the Oni Mask. You can get it in the far better Ninja Nightcrawler set, or better yet, the superior Temple of Resurrection set (and get all the masks!)
Seriously. Do not bother with this set. Spring for the Temple of Resurrection instead. It's what I'm wishing I had done"
