Before I read the reviews of this, I had already pulled the trigger and bought some. Wish I had found these earlier, to be honest.
Camped with my friends, and I'd hang myself high enough that I'd have to hop up slightly to get into my hammock. I'd wake up almost touching the ground, slowly lowering me roughly two-three feet.
I did have the luxury of seeing a friend camp using tie-down straps to tension his hammock, and I managed to pick up a pair for $5. Those have worked wonderfully so far!
