    • Awesome Fun!
I have not done a nice Lego kit like this before, and looking through the construction manual, it looked rather difficult. However, my first impression was wrong. It was an easy build that was very relaxing and enjoyable. And yes, it worked great and there were no missing pieces. Easy to connect to the app and start. The keys, dampers and pedals move as the song plays. It is only two octaves of keys so no, the movement does not coincide with the music, but it is still an amazing build. It is a little rich in price which is a shame, but the Lego quality is evident in the pieces, manual and design. If it is within your budget, this is definitely one you would want to do. ... show more

    • Piano lovers need this!
Dream build. I didn't realize that it would be so big. I had to find a larger display area.

About halfway done. My 6 year old daughter his been into Legos for a couple of years now, so I thought it would be fun to half a project I could work on next her, while she worked on her own. It’s been great. It’s complex enough for it not be dull and mindless, but it isn’t so complex that it isn’t fun. It’s beautiful in design and satisfying to put together. I would recommend it to anyone who enjoys small projects or loves Legos. Also, even though I’m only about halfway through, I’ve already been able to connect to the app and test out the piano play feature. Super cool. Looking forward to seeing it fully together and watching the keys move!. ... show more

This is by far the best Lego I have put together. It takes a little more concentration than some others, as you need to get it right the first time or you’ll be in all sorts of trouble reworking it! It actually plays 👍 It is a great showpiece.

The Lego Grand Piano was fun to build. It looks amazing as a display piece. I was disappointed that you can't play your own songs with the piano. The songs are pre-loaded music that play with the power-up app on the phone, and the keys move up and down. Some challenges with the bluetooth connection. The device inside the piano had to do an update that took several minutes. I had to look into what was going on as there aren't very clear instructions on that part. Overall - a beautiful Lego set to display ... show more

    • Stunning!!!
I absolutely loved this project! I’ve literally never done Legos, and it was no small feat at 3662 pieces, but the instruction book made it very manageable. The packaging it came in was exquisite, and well organized into doable sections. It was so much fun to see tiny pieces come together to create a recognizable and incredibly functional whole. It’s so elegant!! I can’t stop looking at the finished product, sitting next to my own grand piano. I got a separate LED light kit for it, too, as well as a clear acrylic box-style protective cover. The whole ensemble is absolutely gorgeous. This was the most fun I’ve had in ages!! ... show more
