Material Handler Reviews
Brick Architect
“#42144 Material Handler is a fun and engaging set for someone who is relatively new to Technic. The instructions are mostly clear, and the techniques are interesting without feeling overly complex. The set has both mechanical and pneumatic functions which increase it’s... More playability, while it’s striking red color grabs your attention from across the room.”
Brick Fanatics
“42144 Material Handler is certainly a great set overall and has an enjoyable, if only moderately challenging, build process. Those that already have collections of Technic machinery will appreciate the red beams in a change from the more common yellow bodywork and... More experienced builders will admire the skill of the design. Pneumatic-powered sets can all too easily become a rat’s nest of tubing, but in this case the hoses are routed neatly and enhance the look of the model.”

About Technic

TECHNIC is one of The LEGO Company's main lines based on creating detailed model machines and mechanical toys with specialized beams, axles, gears and connectors and primarily designed for older children and adults. The theme was first introduced as the Expert Builder series in 1977, but was officially renamed as TECHNIC in 1984. TECHNIC is still an active theme, and is one of the longest running themes in LEGO history. While most TECHNIC sets are vehicles that use pieces to mimic real vehicles, such as engine pieces, suspension, pneumatic, and transmission pieces, the TECHNIC parts have been used by various other System themes as well as LEGO Mindstorms.
