Retailer reviews
Summarized retailer review data when available.
another proof that a LEGO set is great :)
I bought it because my grandson really wanted it.
A great gift, also for your own child as a reward. The price-to-performance ratio was also good with this offer. For the joy of our son (6), who already has this set 1x and who really likes to play with it and doesn't always want to rebuild it (as it's a 3-in-1 set), he wanted it again. It is really easy to build. Our son was already able to build the first set at age 5, and Lego is simply synonymous with quality and fun. A really great set.
I ordered this for my son and nephew. It's suitable for ages 6 and up, but they loved it because of the robot submarine, etc. The finished size is also very good.
Amazing set , making 3 toys . LEGO Creator is my favorite.Price is fare for high quality.thanks amazon for fast delivery..
