"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 65.3 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.

"I have to say that overall I am impressed with 21323 Grand Piano. Who'd thought that one day we'd have a 'working' piano made out of LEGO!?"

"There's one thing that I love about assembling official LEGO sets the most — that exciting feeling of being lost within such a complex inner structure that you can hardly tell what exactly you are building at the moment. And then seeing how the whole thing comes together and exceeds your expectations is the actual magic of this hobby. But here's the Grand Piano, and it is different."
Owners love the creative build and authentic piano details, but express mixed feelings about playability—most appreciate it as a display model, though some feel misled about its musical capabilities.
