After several failed attempts with special offers and promotional goods of known discounter whose buffers have each held only 2-3 months, then they were worn or broken, I have resorted back to the original buffer. They supplied by Leki in the "original" 18 months on hold. Keep the now as a replacement ordered already around 6 months, without any significant wear. Use: about 2 x / week, about 15 -18 km / week. Solid wood floors, solid forest trails, asphalt, concrete slabs
