These only work with slings as they are too small for ropes. I tried the L size with a lanyard and couldn't get it in. I suspect even the XL would be too small for a rope.
The item is ok but you didn't have as many in stock as your website said and I don't know whether you charged for the number I ordered or the number you sent
Hi, I've used these on a professional basis, they are ok for that but only really as a back up, I certainly would not use these for solo climbing. As a hauling device and also as a back up, they are fantastic but not for soloing, take a partner instead!
