The Full Take
The transformation gimmick is real and it works, but it's the build journey that carries this set more than the destination. Technic fans will find the mechanical linkages genuinely satisfying to assemble — the engineering that drives the shape-shift is clever even if the result looks unfinished on a shelf. At $150 with no minifigs and a final model that reads more 'prototype' than 'showpiece,' the value ask is steep for what you're displaying. The app integration adds novelty but also a dependency — when the app lags or updates break compatibility, that fun evaporates fast. A C+ overall says it all: not a bad set, just one that keeps promising more than it lands.
