BrickEconomy Expert Review
“Arin’s Spinjitzu Battle Mech offers strong value and continuity for fans of the Ninjago elemental power mech line, combining a sleek design, excellent articulation, and a unique color scheme tied to the show’s evolving story. With 213 pieces, a detailed Dark Arin minifigure, a Spectral Dragonian villain, and Baby Riyu, this $22.99 set stands out for its playability and display potential. While not the most essential entry in the series, it remains a great addition for collectors and younger fans alike looking for a character-driven mech at an... More accessible price.”
