I have heard people say it was difficult dealing with 4frnt warranty but I figured it would all work out....I was wrong. After about 3-4 weeks of riding my STL's, I fell on them and bent the core. From my binding up, the ski has reverse camber. I thought it was a for sure warranty. I emailed 4frnt and they said that a bent ski is "pretty much a broken ski" and is not covered under warranty. I think that's wack. They should stand behind their product. I had a small problem with my liberty's and they sent me new ones really fast. Long story short, I am never buying 4frnts again. There's my rant.
