Protector of Earth Reviews
Is this LEGO set a good investment?
“While Protector of Earth has been slightly underperforming yearly growth when compared to other sets in Bionicle, at an average annual growth rate of around 9%, this set is still a decent investment for most LEGO collector portfolios.”

“70781 follows the pattern that's been set thus far by the Bionicle 2015 sets: it's a solid product with more pros than cons, and it upholds the legacy of its predecessors while also offering new and exciting pieces and features. While the Gatling gun feature feels a bit too... More micro for the constraction class, and you're prone to lose all of its ammunition within a few days if you play at your highest level, at least its ammo is easy to replenish. 70781 complements 70789 Onua Master of Earth very well; I'd recommend getting your hands on both of them.”

“The constructed figure has multiple points of articulation in the arms and legs, and comes with two weapons. One is the star drill that lets him bore through any terrain and the other is a gattling gun in his chest that allows him to battle the ominous spider foe. The figure... More also has a dual-tone mask that pops off when you press the trigger, and it comes with a silver skull spider enemy figure.”

“I feel like the Protectors offer a great value by constraction standards. For ten dollars you get at least 66 pieces, including a fully armed figure and a Skull Spider for them to fight. The figures themselves are a substantial size in spite of their cutesy, slightly... More child-like proportions, boasting diverse physiques and even more diverse weapons. And the sets have no shortage of play value thanks to the pop-off masks and rapid-fire shooters.”
