You won them! They're free! Free skis are awesome! Go thrash the shit out of them, who cares if they break? They were free anyway.
Anyway the Trooper is a entry level park ski, the durability is pretty average I wouldn't expect them to last forever because entry level park skis never last long. Pretty much your simple fully cambered park/all mnt ski which will be good for learning stuff on and cruising the whole mountain.
Atomic does make good equipment the boots are great (provided they fit) and the skis are very nice as well especially Infamous and Punx in the park line.
Also if you don't like them you can just sell them on.
