My parents have one. They got it after I had moved out, so I haven't spend a lot of time on it and haven't actually trained on it, but from my little interaction with it....no. It's not a good trainer for skiing. Especially skiing park. It gets you very good at the movement it mimics, but as you well know, skiing is made up of many more different types of movements. You're way better off with more conventional dryland training and knee strengthening.
