Pros & cons
What I actually noticed.
LEGO Icons Optimus Prime
Pros
- Genuinely transforms between robot and truck modes — no parts swap
- Movie-accurate G1 design, not the Bayverse style
- Includes the Energon Axe, Ion Blaster, Energon Cubes, and Matrix of Leadership
- Best-looking Transformers LEGO set by a large margin (vs Bumblebee, Soundwave)
Cons
- Transformation requires patience — first time takes 15+ minutes
- Some joints loosen over multiple transformations
- The hands are clip-on accessories, not articulated fingers
LEGO Icons The Lord of the Rings: Rivendell
Pros
- 6,167 pieces — one of the largest single LEGO Icons sets ever made
- Five sub-buildings, plus the Council of Elrond gazebo
- 15 minifigures including all 9 members of the Fellowship
- Waterfall, river, and full elven-valley landscape detail
- The Shards of Narsil display alone is worth the build effort
Cons
- Footprint is enormous — 72cm × 39cm — measure before ordering
- $500 commitment matches a UCS Star Wars flagship
- Build is 26+ hours — serious time investment
