What reviewers are saying

"A bright fun build, faithful to the source material, and good value for money."

Brickset Reviews

"I think the Dragon has a more interesting building experience, and has more interesting new parts altogether"

Ecosystem

Other Monster Jam sets in the line (six total) — All built to same scale, around 250 pieces, priced at $19.99 consistently. Dragon is first of current year's pair being reviewed.

6617 — 6617 had simpler suspension that felt good to play with, whereas Dragon lacks functional suspension despite being a higher-level build

42150 Monster Mutt Dalmatian — Dragon has more interesting building experience and more interesting new parts; otherwise they offer the exact same level of playability

Max-D (previous Monster Jam set) — Dragon's red half pins with friction for spike alignment work great, whereas Max-D's grey frictionless half pins were practically impossible to align properly
