To export several sets, go to the exporter. If you use the data I'd really appreciate a link back to Brick Insights. It keeps this site going.
A couple negative reviews on this item gave me pause, but I ended up buying this for my son anyway. Granted, he's a little older than 6 or whatever the ages were of the other reviewers, so maybe that made it more tolerable. I've never written a review on Amazon before; it was only because of the negative reviews that turned out to be....misleading...that I thought it only fair to give a positive review. The big complaint was that the thing doesn't stay together very well. For us, it does. Bear in mind, there are parts that are supposed to come off, so they're pretty loose to begin with, but... It's fine. Don't be dissuaded by the negative reviews.
NinjaGo is a strange theme, but some of the sets do look very nice I like the looks and feel of this one for instance though I do feel the price point is to high.
