The Ultimate Darth Vader's TIE Advanced Experience
on July 8, 2026
Posted by: average lego fan
I had an excellent experience building the LEGO Smart Play Darth Vader's TIE Advanced set. From the moment I opened the box, it was clear that a lot of thought had gone into both the building experience and the interactive features. The instructions were easy to follow, with each stage of the build introducing new techniques that kept the process engaging without ever feeling overwhelming.
The design of the TIE Advanced is outstanding. It captures the iconic look of Darth Vader's legendary starfighter with impressive accuracy, from the distinctive wing panels to the sleek cockpit and detailed interior. The finished model is sturdy, highly detailed, and looks fantastic on display. It's instantly recognizable to any Star Wars fan and does a great job recreating one of the most memorable ships from the saga.
What really sets this set apart is the Smart Play functionality. The interactive features add a whole new dimension to the experience, making the model feel much more immersive than a standard LEGO build. The smart elements work seamlessly and encourage creative play, allowing you to imagine piloting the TIE Advanced through intense space battles, defending the Empire, or recreating memorable scenes from the films. The added technology enhances the experience without taking away from the enjoyment of building with LEGO bricks.
The quality of the pieces is excellent, as expected from LEGO. Everything fits together securely, and the completed model feels durable enough for both display and play. I also appreciated the attention to small details throughout the build, which made it rewarding from beginning to end.
Overall, this is one of the most enjoyable LEGO Star Wars sets I've built. It successfully combines an engaging construction experience, interactive Smart Play features, and an incredibly faithful recreation of Darth Vader's iconic TIE Advanced. Whether you're a longtime Star Wars fan, a LEGO collector, or someone looking for a fun and interactive building project, this set delivers on every level. I would highly recommend it to anyone looking for a build that's both enjoyable and impressive once complete.
This set had many cool sound features, and I would definitely buy more copies of this set!

Super fun!

We thought this set was amazing! The build was fun and easy for our 3 year old to follow along. He loves playing with the set. The big benefit as a parent building was… ZERO STICKERS. Made the whole thing much smoother. Is it expensive? Sure. But our son loves it beyond the build.
I would recommend this to a friend!

Super fun Lego set!

[This review was collected as part of a promotion.] This Lego set is really cool! The magic brick is such a fun new addition to these sets and I appreciate that this set came with one. The instructions were easy to follow and my kids had a lot of fun building. The extra sounds make it feel like you're making your own Lego Star Wars movie.

DON’T BUY. SAVE YOUR MONEY
on June 20, 2026
Posted by: sanosg
I had gift cards and I saw this set. Had NO idea what “smart play” meant but turns out it is a brick that lights up and gives you sound effects. Not official sound effects either. And it is only for playability so the set, the ship, is not complete. It has an open back to take the light up brick in n out easily.
I wish I had never got it. It was an awful build. Left me with too many separate parts, not good for displaying, and I couldn’t return it because I’d used gift cards to purchase this. AND, couldn’t collect points for building it because the QR Code was for a different set!!!!
Waste. I will box it back up. Don’t want it on my shelves.
No, I would not recommend this to a friend.

On the right track
on June 7, 2026
Posted by: ricketybricks
I love the concept of the smart brick and I think Lego is headed in the right direction, but the execution here is lackluster. My hope is Lego will at some point enable us to design our own features via the app or with next gen bricks/tags. It's hard to imagine the toy company that brought out my most creative self as a kid and gave us MindStorms would make a new
technology so restrictive. It also seems counterintuitive to me to make such a rudimentary design targeted to juveniles and launching it via a 49 year old movie.
The other more traditional parts are of a similar quality to what Id expect from Lego. But the bottom line, after nearly a lifetime of playing Star Wars, NOBODY makes better laser sounds than me. Pew! Pew!

[This review was collected as part of a promotion.] My six year old son and I are working on this Star Wars LEGO set together. He is a huge Star Wars fan and was thrilled to get started on it! The design is detailed and it is a fun family project. We are excited that this set comes with a smart brick and can’t wait to hear the sounds and see the lights. Highly recommend this set for Star Wars fans!

So glad to finally get this set! It was packed excellently, with a special part for the SMART brick and charger. Building it was amazing, and the play is great! It responds incredibly well to motion, color, etc. I'm very happy with this set! can't wait for more Smart play!

Brick stopped working
on May 17, 2026
Posted by: SmartPlaySucks1
Terrible value, makes terrible sounds, terrible quality. My brick stopped working the second day I had it. I left it on the charger overnight and when I tried to turn it on the next time it didn’t work. 0/10 I would give it 0 stars if I could
No, I would not recommend this to a friend.
