Great item for people with oxygen bags. My husband uses it when he goes out to keep his oxygen tank of the floor. The ring is sturdy. I only wish there was some sort of locking device to keep it from coming off unexpectedly when not in use. He leaves his bag on all the time and we are now on our 4th ring in 5 years.
Pros: Good quality, strong, nice finish
Cons: needs a locking system to keep it from getting loose from the bag when not in use.
