Fun to build

GemmaH May 8, 2026

[This review was collected as part of a promotion.] It has been an interesting build the app on the phone works better then the paper instructions. The ammo that shoots out goes quite far and not great to find on a floor as they are small. The lights and sounds are great features and the size is good for putting on a shelf somewhere safe, overall the durability is good but the bottom of the wings come off quite easy when putting the smart brick in but they easily click back on, the value of the lego set seems ok for everything that it does.

Very life like

SelmaT May 6, 2026

[This review was collected as part of a promotion.] My son absolutely loved putting his Star wars lego set together. The pieces are of good lego quality, the pieces are of a good size and weight to put on show once put together. Will be an absolute wonderful gift to all ages.

Enjoyable

LauraR May 5, 2026

[This review was collected as part of a promotion.] Darth Vadar Tie Fighter has been such a fun build the features are brilliant, kept us entertained for a few hours. The mini figures are the best from the star wars set, down to the small details this has been a great build. Really enjoyed it. Very creative. Great price too.

May the Force be with you.

DestinyB May 7, 2026

[This review was collected as part of a promotion.] It's been a blast putting this together! The design is really impressive, capturing all the iconic details that Star Wars fans will appreciate. Playing with it has been so much fun. It truly feels like I'm 10 again creating something magical. The interactive features are what really make this Lego set stand out. It responds to different movements and sounds, which adds an extra layer of excitement. My kids love pretending they're in epic space battles, and I have to admit, I enjoy joining in on the fun too! All in all, it's a fantastic toy that sparks imagination and brings a bit of the Star Wars magic into our home.

Loads of fun

JoshuaF May 13, 2026

[This review was collected as part of a promotion.] This Lego Star Wars Tie Interceptor set was was so fun putting together with my son. The instructions were clear and easy for him to understand and the pieces were separated in step by step bags to streamline assembly. They have stayed together and survived several days of play without requiring any maintenance or reassembly. I HIGHLY recommend purchasing!

Fun fun fun

AmandaJ May 13, 2026

[This review was collected as part of a promotion.] This was so easy to build. The hardest part was waiting for the smart brick to charge (even though it wasn't long). My son loved blowing able to add sound with the smart brick. He really enjoyed it.

Good product

FinolaF May 18, 2026

[This review was collected as part of a promotion.] Greta set for Star Wars Lego fans safe for older children and adults but keep away from young kids due to small parts seems like a good Lego set but don't really rate the smart brick technology currently feel the sound quality wasn't as good as id hoped

Great

LauraR May 11, 2026

[This review was collected as part of a promotion.] This was my partners favourite to build instructions were straight forward. Lights work. Some parts were a bit awkward to fit. Light weigh. Great bonding for my son and partner they enjoyed building it
