As a long time Lego builder, this was my first light set (also bought the new Hocus Pocus light set at the same time). Shipping was quick, order was mailed hours after ordering on a Friday and arrived Monday afternoon. As some have said, the install can be difficult. I had no issues connecting the extension wires into the different boards, but every one of the small LED lights gave me issues when connecting to a board. It took working on this for a couple hours over a few nights, but once I got everything connected, it all worked as advertised, minus the elevator. Just when I thought I was done and went to test the elevator, wires from the first few lights installed in the kit were getting caught and prevented the elevator from going up. I had to dig into my dash for spare bricks to hold the wires down and even broke apart a wall to re-route the wires to tuck them out of the way better. Some of the wire routing could've been better to tuck them away neater or not interfere with the bricks seating on the plates properly. Maybe future install experiences will be better for me and I'm looking forward to the Hocus Pocus set, and will likely cave in for more lights for holiday sets, but just know going into this, install may take more time than the initial set build did and have some patience for those pesky connectors, especially if you have bigger hands/fingers.
