J.B.'s Ghost Lab

"J.B.'s Ghost Lab earns its Mixed Reviews verdict as a set where the minifigures outshine the build: experts find the lab structure incomplete and app-dependent, and the LEGO.com owner recommend rate of 74% confirms this is not a universal crowd-pleaser despite strong Amazon scores."

The 70418 J.B.'s Ghost Lab sits in Mixed Reviews territory, reflecting a gap between its appealing minifigure lineup and the limitations of the physical build and its app-dependent play model. Expert reviewers from JANG and Brickset both found the lab structure itself modest and incomplete-feeling, particularly the ghost chamber, while praising the detailed minifigures and small-build density. Owner data shows a notable split: Amazon buyers rate it 4.7 out of 5 across 1,822 ratings, but LEGO.com reviewers land at just 3.87, and only 74% would recommend it, hinting that app compatibility issues frustrated a meaningful segment of buyers.

Where they split: Expert critics (JANG 70, Brickset 65) see a competent but limited small set held back by its ghost chamber and reliance on app access. Amazon owners rate it 4.7 out of 5, but LEGO.com buyers sit at 3.87 with only 74% recommending it. The app compatibility issue appears to drive the lower end of owner sentiment, creating a real split between satisfied and dissatisfied buyers.
