    Stunning piece of art

    I would recommend this to a friend!
    Purchased for: Self
    I have built many of the Creator and Ideas series, and this is by far my favourite Lego build... period. The detail is exquisite: the counterweight key action with hammers, the dampers, the sostenuto pedal, the little lip on the edge of the keys, the little red 'felt' band on the keyboard, such attention to detail shines through every step. The amount of SNOT work is astonishing. You can tell this was designed by a pianist. Yes the building of the keyboard was a little repetitive, but I worked a system for rapidly building the keys. I agree with some of the reviews that it is not actually 'playable'. Come on, it's a Lego model, think what would be involved to add a sensor to every single key to actually play it. Perhaps slightly misleading of the way it's advertised, but not a reason to give 1 star. To the reviewers who complain about the motor making a noise - what do you expect, it's a motor. Some have said their motor and keyboard don't work and get stuck, I've not experienced that, and it resets to a flat keyboard absolutely fine. To the reviewers who give 1 star because it was out of stock -- ????? Hardly a product review. This is an amazing build - but I guess more so if you have an interest in pianos.

    Raced Through It

    Overall, I am quite happy with my purchase of this beautiful piano 5 minutes before it was released. The process was quite straightforward and I didn't have any difficulties racing through it as I had memorised the instructions for majority of the piece with my pianistic memory. I am definitely happy with the result, although I would say the mechanics need some time to loosen up for the keys to work smoothly. I love the overall size, although @Lego, this is considered a Baby Grand rather than a Grand Piano, maybe consider enlarging the product into a 9-foot concert grand next time? But overall I love it and am happy that I stayed up to get it!

    Great to hear you enjoyed building this set, and thanks for your feedback on the name. A 9-foot piano model might be a bit too grand for a LEGO® set, but we'll make sure to keep the naming tip in mind!

    Wonderful detail, iffy mechanics

    I guess I lucked out and hit my local Lego store at the right time to purchase this Grand Piano. I saw it advertised on a classical FM Facebook page and knew I had to get it. Construction was smooth, if a little tedious due to the repetition of making 25 working keys. The overall look of the piano is amazing and true to detail. My only complaint is in the mechanics. The motor doesn't always turn the spindle for the key movement and will get stuck. There is a function to reset the keys to a neutral position and that doesn't work. The motor also has a very high pitched whining noise that takes away from the enjoyment of the music. Regardless, i highly recommend this model if you can find it.

    I really like this piano, I’ve been learning to play for nearly 10 years so this set was very well received. I think it’s brilliant, the reviews who say you can’t play it, I’m not sure what they were expecting for the price tag? It’s a model piano!! I loved building it and when you connect your phone for it play is just brilliant, there are a lot of pieces and some repetition like the keys but it’s not off putting at, I loved building it, and I find it amazing how it works, even the stool is adjustable! definitely recommend.
