To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I bought these because they're the only ones I could find that can go around the 11-foot circumference of the oak tree in the backyard. I put a post in the ground as the second side. The straps did great around the tree. The one around the post failed when my wife and I got on the hammock. We are about 400 pounds together. The strap lurched and the stitching came out. I returned the broken one and promptly got a replacement. So far, so good, but can't give you 5 stars for the first one's failure.
