These rings are on the thin side (compared to Olympic Rings). They are durable and high quality. If you buy these make aware that you will have to tie a knot. There is no adjusting. I am going to buy the adjustable ones so I have more exercises available.
Fits comfortably and can hold my weight. If you're getting this learn to tie a knot since there is no clamp or pin to hold it in place, but if that's fine for you then go for it.
These rings can't be beat for the price. They are a very tough set of rings that you won't have to worry about beating up. I hang mine from the Power Rack at varying heights for all types of different movements.
