ive never had one for a camera, but i had one for my ipod. it was sick. i took a nasty spill on my pocket where my ipod was and the screeen cracked and messed up. jsut took it to best buy the next weekend, waited for like 2min in line and then the lady at the customer service desk gave me a new one. all i needed was my repicet and to tell them it was broken.
like if you think you going to break it its totally worth it. so with skiing , it makes sense. if you replace it once it pays for itself. id do it. its protecting your camera
