It was a life saver. My wife's ring stayed so tight it wouldn't come off no matter how hard we tried. We tried all available methods. It got to the point where the circulation in her finger almost stopped. We even called the jewelers around us and they said they wouldn't cut. After checking out Revain I bought this one. One day I received it, used it and successfully cut the ring off my wife's finger. So with relief. If you are in a similar situation I would definitely recommend this.
