"I found this on Amazon two weeks ago and got straight to it. Took me 27 hours and 20 minutes over two weeks on and off, during which there were definitely some difficult and frustrating moments which paid off. With over 7000 pieces, each of the 17 stages comprise at least 3 main bags with several more smaller ones within, meaning a lot of time was spent sorting through to find small pieces or forgetting that I'd put a bag aside and thought I was missing pieces.
The level of detail on the exterior is impressive, particularly around the perimeter. I haven't played with Lego since I was a kid, but I was surprised to see the revolver gun piece pop up in this set; even more in how it was used.
Several of the top panels can be removed to showcase some interior features, which includes corridor stickers and some nice portals.
While you have to be careful with how you pick it up, the sheer number of pieces for detail is reflected in the weight of the model.
"The piano set is a fantastic build. It's hefty but structurally very sound. During the build there were a few moments I thought it would fall apart, but these elements are reinforced significantly by technic pieces. My only complaint relates to the software wherein the red reset button doesn't work reliably. Other than that, it was a fun experience."
