I've owned this ring for over a year now. I always get compliments on the unique design. I have never had it scratch or had the embedded carbon fiber shift or come loose. I believe that tungsten will gain popularity in the coming years among more discerning men for its unique look, high durability, and low relative cost.

Update 11/2013: Two years later, the ring still has its shine. I continue to get compliments, and I'd definitely purchase this again. A word of caution, though; as my friend found out, Tungsten will shatter if it hits a ceramic tile floor. It's something about resonance. Be careful if you take your ring off to wash up!
