Hawkinswrote a review of MSR CamRing Cord Tensioners on March 23, 2018
I just received these a few days ago, and haven't even had a chance to use them yet. But the cheap plastic ones that manufacturers send with every tent, and all the others I've seen online, they make my head hurt. These don't make my head hurt.
All the other brands, you mostly can not figure out how they work until you actually use them. I don't want that. I want something that I can hold in the palm of my hand or look at a picture online and say to myself: "Oh okay, I can do that." or "These will work."
