This is such a fun set that highlights the adorable elf minifigures. I love their new costume design and the red scarf. The little computer build is one of the highlights, so incredibly cute and perfect for an adult set since only adults will recognize these old-time computers :-D I did swap out the "keyboard" for a printed one from my own collection. The pirate ship, plane and piano builds are fun as well. The Christmas tree is one of my favorite tree designs yet. I love the colors, sand green and dark tan. The roof design was very smart and looks great. It makes displaying next to the Gingerbread House cohesive. The waffles are a really great printed piece. A clever build for the waffle dispenser station and the beds that shake. The light brick is also a nice addition and the green round 1x1 plates were clever for the wreath. And the deer has to be mentioned, so happy for one of those. I was a little disappointed at first that there was only one deer, BUT it's not a deer for Santa's sleigh, it's just for the little elf sleigh so it's perfect. I do hope more will show up in other sets to collect more. While considered one of the adult sets, playability for the kiddos is excellent. I gave this four stars because I don't care for the dark instruction book. I will say that the darker colored bricks were hidden by the dark pages and it threw me a bit from time to time trying to figure out what color I was supposed to use. For example book 1, the tree build starts with a dark green plate, but then the next instruction showed two green plates. I completely missed seeing the dark green plate was actually underneath the green ones. Seeing the difference between tan and gold was tough at times, too. And a transparent piece is always tough to print, but I was searching for a gray one and when I couldn't find one, I discovered it was just transparent. I understand wanting to match the dark boxes and their nice design, but LEGO, I say stick with what works. When putting your sets together, the instructions are important which in turns means that seeing them well is very important for the fun-factor. All in all, another well-done and popular Christmas set!
