I purchased 2 sets of these (4 straps) to use to secure bags to my motorcycle. They are clearly very high quality straps with well made and sturdy buckles. That's why I gave them 5 stars. I have tried other brands and the buckles were very light weight. These buckles are sturdy and well made. One caution - two of my four straps were not well terminated and when I tried to thread one of the straps, it quickly became unravelled (see photo). This was a very easy fix - just trim the strap and re-burn the edge to seal it. I guess the edge burner had the day off when two of my straps were made. Since I was planning on cutting the strap to shorten it didn't matter to me, and the fix was very easy. I still give five stars because these are clearly quality straps, I would just caution you to inspect the loose ends of the straps before you use them to make sure they are well sealed and will not unravel like mine did.I didn't comment on durability since I only just received them, but will update this review after a few serious uses to comment on their durability. Based on the obvious quality of construction, I don't have any concerns at this stage.
