UPDATE 1/12/25-I posted a review about lingering builds that won't clear. I tried to use the reset button but it didn't seem to work. Marine, from LEGO CS, mentioned it in her response, I tried again & it worked. Thank You Marine! However, there is a lingering issue with the app just crashing & my tablet is compatible. Outside of that, I enjoy the app & ease of use with instructions (pdf & 3d), although 3D needs options like stop animation, better skip or pages for quick access. Was 3.5 stars :)

Love the ability to manipulate the 3D models in the instructions! Often (the printed instructions) will have a piece that is critical in the direction it faces, but it isn't obvious in the illustration, and you won't know until several steps after, and then need to disassemble to fix.
