I picked these up to add to the gear and the climbing possibilities. Very happy I did! I do like these more than others because of the smooth operation. Even starting out at the end of the rope with a light pull of the "trigger" it glides up the rope nice and easy and locks solid. Have not tried with wet or icy ropes yet, but I would imagine the same performance. I paired mine up with the metolius easy aiders and wow what a perfect combo!
