Criminally underrated5/5

The Lego Ideas Grand Piano (3662) sparked some controversy when initially released. Lego advertised the set as playable when using the companion app when in reality, the functionality was exaggerated and is extremely underwhelming. That said, the Lego Ideas Grand Piano is probably the single classiest display piece The Lego Group has ever released, still featuring a ton of impressive play functionality. While pressin

I should have known. I would hig

Box and Packaging The large, densely packed box is mainly Black in the current 18+ style with a lid/base rather than the usual flap ended box. When the model is fully built, it can be slightly disassembled and packed away in it. This is genuinely a plus point for me, as often completed models can't be put back into the box for storage. There are multiple bags, numbered 1-21 (some are in a secondary internal box) and
