I've noticed one hassle so far. If I pull it really tight, then want to undo it before I get in, the buckle is tough to undo.
I was just going to post about this when I read your comment. I was playing around with the buckles AND a ridgeline trying to what they are all about. I was also using overly long straps stretched out to a silly distance between trees. (I know, too many variables at once) So, naturally, I had to pull the straps really tight to keep my butt off of the ground. I was completely unable to release the buckles. I had to cut the ridgeline to get enough slack. It was fortunate that I was also playing around with a ridgeline at the time, or I would have had to cut a strap.
