My son loves it. It swims well and the parts are top nodge. the doors go a little heavy so that one has to remove the ceiling and open them from within. The crane is super cool.

Good quality , BI on some pages weren’t detailed but we could build.

My kid loved it, everytying was in order.
Bags aren't numbered though so building can be a bit tedious...

815pcs 66117 Arctic Research Ship

Bricks, color quality and clamping force as usual very good.
The hull of the ship had a few scratches, but these could probably have been on the original as well.
A steering wheel was missing (no matter)
My son got it for his 6th birthday, he had no problems with the build (ok, maybe the clamping force is almost a little too good for small children), he is very happy with the set and plays with it a lot
