Unless you feel like donating to the mountain, don't buy.
Stuck it, put weight on it for 24 hours, and it was still floating around when i poked it. Took it off, recleaned, and bought a new one. This time held a heat gun to the glue, stuck it with, waited 48 hours with books stacked on it and went snowboarding. Fell off at the summit the second i got off the lift. Now it's buried under 3 feet of snow. what a waste.
