“I think this is a fun jet set, and while it does have some flaws, none of them outshine the overall model. I think Ninjago fans will very much appreciate this set, especially now that we're getting Kai with hair. I think Space fans will also like a new jet design, which has... More a very futuristic spaceship-like feel to it.”

“Overall this is a fantastic set. It’s mostly Red so it has to be, right? It makes it go faster too. This was a really fun build that has some great SNOT* building techniques. I really enjoyed building the adjustable wings feature, it was incredibly well thought out.”
