First day of using, at the end of the ski day, clipping the second pole into the Clipstic it fractured. I was pretty cold, and it seemed like the plastic had hardened significantly. The customer service team sent a replacement which I received about a week later.
The way the poles mount they interfere with the binding brakes causing the poles to be skewed out. Certainly make the whole assembly (ski, clip, poles) a bit more cumbersome and a pole tends to pop out. Great concept, needs refinement
