So, friends!, here are the 2 sets that I bought.
First let's start with set number 4473, Research Submarine.
I love this set. As I said before it is almost perfect.
the design is very well done, from shape to colors, from clickies to features.
The clear bubble cockpit is awesome and very realistic. The battery motor is very well adjusted to the general design and it does feel as part of the submarine. This does not happen in the rest of the water vehicles.
The details are really great.
The motor detaches joined to those tray-like things on the sides. Those are made of metal as well as the "tanks" on the belly of the submarine. Of course they are meant to sink the ship.
The top part or roof if you will can be taken off to insert the clickies. There is not much room in there but that is realistic too. It has a clear window to look inside. The roof is locked in place by the "triangular" piece that rotates permitting to take off or to lock the roof.
The submarine has two lateral rotating propeller, two movable front lights and two working arms. Again all this great to play.
The inside is narrow, just enough room for the clickies to sit. In here I see a flaw. There is no stickers for the console. I guess it is because the cockpit gets full of water when diving.... and that is the other flaw. I wish it wouldn't.
The arms have grabbing hands, very cool too for playing.
The clickies are excellent. I love the clothe design and colors. The only silly thing I didn't like is the girl's white ribbon. I just don't find that necessaryfor a scientist
In my opinion the best modern life set that I've ever bought.
