One mom said, "Purchased this as a gift for my mega BTS fan daughter, who also likes Lego, and it was a big hit! She assembles a lot of Lego, even so, this is an easy assembly for someone who has never put together Lego ever before. Everything about this set is great."

"I love this Lego set! It’s a cute addition to my growing PC desk setup. It will add a nice flair to any corner you place it on. It took me like 2.5-3 hours to build, very easy!

There were no missing pieces, instructions were really clear and the Lego set is just beautiful!" one five-star shopper wrote. 

With more than 3,000 pieces in all, this set isn't one you're likely to knock out in a day, but once finished, it'll look great and give out some serious Swiss Family Robinson vibes.

"My son got this for Christmas and he spent about 12 hours building it. The instruction book is huge. He loves this set so much. He has grand plans to use it to make stop-motion videos and all kinds of things. The set has so many little details when you start looking at it. Each room has little details like flooring, decorations and more. ... Well worth the money so far," said one parent.

No one can argue with the fact that some of the coolest Lego sets out there are part of the Star Wars universe, and this 561-piece kit from The Mandalorian backs that up. Also awesome: This is the lowest price ever for this set at Amazon!

Calling all movie buffs: The DeLorean from Back to the Future is available in Lego form! It includes 1,872 pieces and is intended for adults (18+), so take note: This is not an easy build. Once assembled, you could try fashioning a motor and taking it up to 88 miles per hour, but we claim no responsibility for what happens. 

"As a lifelong fan of the Back to the Future trilogy, the Lego Icons Back to the Future Time Machine set was an absolute dream come true. From the moment I laid eyes on the box, a wave of nostalgia washed over me, and I was instantly transported back to the countless hours I spent as a child, and as an adult, lost in the world of Marty McFly and Doc Brown," said one happy shopper.

If you're old enough to recognize this set, then you're old enough to build it (and hopefully, have a good enough job to afford it).

Only changes I think would have made it better are adding Ellie's chair and making a customized mailbox with a print of Ellie and Carl's handprints and names like in the movie. For its smallish size, it is jam-packed with items that fit in with the movie. For the price, it's an exceptional value and one of the cutest sets ever! A must-have for any age!"
