Pros & cons
What I actually noticed.
LEGO Icons Ghostbusters Ecto-1
Pros
- Iconic 1959 Cadillac Ecto-1 silhouette with movie-accurate proportions
- Working sirens (visual rotation, not lit)
- Equipment bay with proton packs, ghost trap, and PKE meter
- Opening doors, hood, and trunk for full interior access
- Roof-mounted equipment is removable for transport-mode display
Cons
- No included minifig (it's a vehicle, not a vignette)
- Some sticker work on the side panels and windows
- Size demands a wider shelf than the [Land Rover Defender](/reviews/land-rover)
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
