Grand Piano

"The Grand Piano earns its Mixed Reviews tier (BrickScore 65.3) because it is genuinely two things at once: a visually spectacular display piece that most builders love completing, and a motor-driven key mechanism that a real share of owners find unreliable after completion. At $399.99 it is a purchase that rewards patient, display-focused builders while carrying real risk for those whose primary interest is the auto-play function."

The LEGO Ideas Grand Piano (21323) carries a BrickScore of 69.2 and a Mixed Reviews tier, reflecting a genuine split between its stunning display presence and its troubled functional mechanics. Three Brickset ratings are uniformly positive, and the majority of LEGO.com owner reviews praise the build experience, detail, and visual result. However, a notable minority of owners report motor sticking, key misalignment, app synchronization issues, and a lid that fails to close properly, pulling the consensus toward caution. Owner ratings at 4.69 out of 5 from 1,876 reviews are higher than the expert score would suggest, but the lego_signals value-for-money figure of 4.1 and an 86 percent recommendation rate hint that a meaningful share of buyers found the $399.99 price hard to justify given the mechanical reliability issues.

Where they split: The split between critics and a minority of owners is the central tension here. The Brickset ratings and a majority of LEGO.com reviewers are purely enthusiastic. However, a meaningful subset of owners report motor and key-alignment failures significant enough to break the set's core function. The aspect consensus scores this explicitly: display_value is 81.8 while playability is 43.2. Buyers who prioritize the display and build experience will be satisfied; those who bought it for the auto-play feature should be aware the mechanism is not universally reliable.
