Absolutely enjoyed it!

aqsafm_8874 December 27, 2025

[This review was collected as part of a promotion.] Received this wonderful Lego Technic Deep Sea Research Submarine from Influenster in exchange for an honest review. The instructions were clear and easy to follow. The parts were complete and nothing was missing. Me and my children thoroughly enjoyed building this Submarine. It was an absolute delight to watch the final outcome!

Amazing!

jennncore_561 January 23, 2026

[This review was collected as part of a promotion.] My son loves building Lego, but he hasn't tried Technic before so this was like a little level up for him! Some bits were a little more fiddly and needed some assistance, however, the result is so cool! He absolutely adores it!

Great for kids and adults

beckyw102_2926 December 12, 2025

[This review was collected as part of a promotion.] I love this lego set! This would make the perfect gift for kids over 9 but also adults. It's one id their smaller sets, so not too time consuming but just as fun to put it together. It has a number of moving parts, but it easy enough to assemble. It's a really interesting set from Lego!

Great for technic builders! Harder for children

eeveequeen_2423 December 11, 2025

[This review was collected as part of a promotion.] The Lego Technic Deep Sea Research Submarine is a fantastic set for both Lego enthusiasts and fans of underwater exploration. This set falls into the higher difficulty range for Technic builds. Some smaller parts and advanced mechanisms require patience and focus, but it's all part of the fun for experienced builders. The best part of the Lego Technic Deep Sea Research Submarine is the satisfaction of seeing the moving parts in action after completing the build. Plus, the finished model looks great on display! It's a lovely smaller build and it was really fun to build. Assembly is a little harder than normal technics but it's absolutely fine. It's nice to hold too and doesn't weigh anything!

Detailed and fun!

GassySardine059 January 2, 2026

I love the features and details in this: the tilting and spinning propellers, the retractable claw arm, the opening hatch, and more! The only negative is that the arm is a bit loose due to some play in worm drive, but that's a small matter. All in all this is a great set with cool style that's fun to build and play with.

Great build

laurac668_9752 January 1, 2026

[This review was collected as part of a promotion.] A great Lego set! Love how straight forward the set was to assembly and the packaging all eco friendly. Good difficulty to build. A stable design and like the difficult it has. Fun and interactive, designed for both younger and older people. A stable design - really love it! Lego never disappoints.

Great :)

girlnextdo00r_6922 December 14, 2025

[This review was collected as part of a promotion.] The LEGO Technic Submarine has been a fantastic addition to our home. My child absolutely loves playing with it, especially because it's so interactive. The moving parts really bring the submarine to life and keep them engaged for long periods of time. It's not just fun to build, but also fun to play with afterwards, which isn't always the case with building sets. The design feels sturdy and well thought out, and it encourages creativity, problem solving, and hands-on exploration. Overall, this set has provided hours of entertainment. If you have kids that love mechanical style toys, this is a good choice.

The details are impressive and the finished submarine looks sturdy and well designed. I love the moving parts and accessories, which make it great for imaginative play as well as display. The pieces feel high quality, fit together perfectly, and the build keeps kids interested from start to finish. A brilliant set for anyone who enjoys LEGO or ocean-themed adventures.

Great Lego set

skinlovesbysam_8443 December 17, 2025

[This review was collected as part of a promotion.] My son really enjoyed putting this together. It's great shapes & sizes of ego that fit together to make a submarine. The instructions were easy to follow & made of bright coloured pieces. It has a few different functions too so makes it a great product for younger boys. I think 9 is a good age to start this as any smaller children wouldn't be able to follow the instructions. A great piece for older children, boys or girls !
