Have just completed this model, working only with the instructions, and had no problems at all. The model is impressive and works well. This is the second model I have made, my previous one was the clock which works well and again recommended.

Got this one for Christmas! Perfect present! Loved assembling it!
Only two recommendations: not written in the instruction that you have to pay attention in which way to install big wheel (so marbles can enter it) and we had to adapt marble-stop as they fell under the lift.
Would be great if you would sell an electric gear for it!
Got already next one😊!

I just finished it. Took around 4 hours. Some parts needed glue or else they popped out. Had to fiddle with the bottom of the lift so the balls would get stopped and not roll into under the lift. Best way to fix it was push the final bit of the marble run a bit closer to the ball stopping mechanism. Looks really cool when it is running. Was fun, and challenging. Would recommend. Now to add an electric motor to it for auto mode.

Excellent model, well put together. Videos not very helpful, but instructions good enough to get thru. Some parts in the instructions where not represented and the part number was not displayed. A better construction order would help, placing some of the interior parts before those on the outside. Instructions not as good as LG504.
