Lauren P.wrote a review of Petzl Dragonfly 8.2mm Half Rope on May 9, 2012
These ropes are bad. The very first time I used them the sheath tore exposing the core of the ropes. This was from normal wear and tear - no falls or sharp edges. I sent the damaged ropes back to Petzl for warranty and they could not offer me anything; not even covering the shipping cost for the return. I now learned that other people have had similar problems with Petzl ropes, so I recommend you avoid Petzl ropes altogether.
