Replying to Kitten Factory

My friends brother co owns this ski company called kitten factory. I'm thinking of getting a pair of there park skis ( the razorbladez) my friend let me test em out one day and I like everything anoint them. The only thing I don't know is if they are durable or not. If any of you have a pair or know someone with a pair please tell me if they are durable because 600$ is a lot for me and I don't want to break them in like a month. ( I know that a ski you don't take in the park is a durable ski. Sliding all sorts of rails and jumps will take a toll on any ski no matter how durable so based on that me if they are) thank you
