Not one of my favourite kits and I only bought this because I wanted the stingray creature that is included. Normally with the 3 in 1 sets I end up buying more than one so I can do the additional builds but with this one I already have a number of submarines and the ancillary builds just didn't interest me. So, just bought the one and figured the robot will look okay next to my Exploration Base. He not only looks okay he actually looks pretty cool. One of those unusual occassions where the box art actually makes the figure look worse than it actually builds to. I really love my little robot guy and the fact his "claw" works to grasp things is a nice bonus. The stingray that I bought the set for is everything I hoped it would be and holds up well against my other deep sea creatures. The robot is a fun build and looks well on the shelf with the other underwater items. Definitely a great robot for playing as he is really articulated well.

Instructions are pretty good. My six year old is able to read them and put them together. Keeping him focused is another question, but that has nothing to do with the toy. The prices for these types of toys seems too high for what you get, but that is true for Legos, too.

This set is pretty generic 3-in-1 fare, unlikely to garner much attention from AFOLs or LEGO fans that aren't into underwater machinery. That said, it has three very different models that are still enjoyable to build. The yellow colour palette is bright and inviting, and there are some nice parts here for those looking to MOC once the models have been built at least once. One to buy on impulse or if found on offer, if not there are other sets within the same price range that might appeal more.
