"Kai's Ninja Climber Mech justifies its Recommended BrickScore of 77 as one of Ninjago's more athletically designed mechs, with a sturdy posable build and four excellent minifigures, though buyers sensitive to size-versus-price should note it builds faster than its $69.99 price tag suggests."
71812 Kai's Ninja Climber Mech earns a BrickScore of 77 in the Recommended tier, with The Brothers Brick calling it one of the best Ninjago mechs for its efficient use of 623 parts to create a stable, dynamically posable four-armed design. Owners are enthusiastic, averaging 4.87 out of 5 across 636 ratings on Amazon, Walmart, Target, and LEGO.com. The one meaningful friction point is price: LEGO.com's own value-for-money signal sits at 4.29 out of 5, noticeably lower than the play score of 4.81, and multiple reviewers noted the $69.99 feels slightly high relative to the mech's size.
