The skyline looks awesome with the addition of the light kit. You will see the wires but you can route them in a way that makes them a little more discrete. Also, on the Willis Tower (it will forever be the Sears Tower in my world but I figured I should be PC for this review) the bricks will definitely have gaps since you have to run the wires behind them as you go up the tower. The non-flush look is a little difficult to deal with since Lego is so good about engineering their bricks to snap together tight and perfect, but if you take a little time to line up the gap/wobble it doesn’t look too bad. It also helps that the gap/wobble is on the black bricks because it helps hide the imperfections. Typically, you aren’t right on top of the Legos as you view them anyway so for me the benefit you get with the addition of the light kit far outweighs the look of the wires as well as the gap/wobble of the bricks. I am curious to see how a light kit works on something other than a landscape (architecture) build as I also purchased the Las Vegas light kit, which also looks awesome, so I will be purchasing the Home Alone kit next. With all of the light kits out there it is also difficult to decide what company to go with but I have reached out to LeLightGo’s customer service department a few times with some general questions and they actually responded to me unlike other companies and their response time was within 24 hours. To me that is super important because I felt like they actually care about their customers and not just selling products.
