I work in Maritime Industrial Support as a Field Service engineer. Working around Propulsion and Electrical distribution equipment my wedding ring was one of the very last things that I wanted to take off. My wife found these for me. The silicon rubber is a perfect solution to eliminate the shock, de-gloving, and amputation hazards often seen in our line of work. These rings allow me to display my commitment to my wedding vows without sacrificing safety to myself, co-workers, or the equipment. Best yet ThunderFit, I feel, went above and beyond to make sure that I got a perfect fit. Robert and his team emailed me to make sure that I was completely satisfied with my purchase. If you are a technician in an electrical or mechanical field that wears a traditional wedding band, I HIGHLY recommend this low-cost alternative and THIS company to provide you with them. The sizing for the silicone ring was the same as my gold wedding band.
