This is a good 3 point sling. I can't say much on prolonged use of it but the set up and training goes well with it. It fits many different set ups and I found can be used on more than just the AR platform because of the many attachment options. The sling is thicker which is easier on the shoulders than others but makes it a bit more difficult to do a forearm-wrap and I wouldn't recommend it with this sling. So far is pretty durable and takes more time than other 2 point sling to set up and adjust but that's the product. Also recommend taking some time to practice using the sling in terms of carry to ready positions.
Pros: Lots of potions for different set ups depending on your platform
Cons: like with anything need some getting used to and practice
