Tungsten Carbide here as well, takes anything you can throw at it, people always ask me how often I clean it, as it has no scratches and looks brand new. I have put the ring through hell (working in power plants, working on my car, skiing etc) it still looks perfect and I havent cleaned it from day one.
you get used to the weight of it as well, hand felt naked and still does without it. god help you if you get your hand stuck anywhere lol
