My husband and I both have these rings and wear them 24/7 and they look like new.  We both originally had comfort fit Tungsten bands that were about 5 times the price of these and these are holding up just as well as the others.  The down side to be aware of with tungsten is that you can not have the size alerted so if you ring size changes you have to get a new ring.  But at this price, it is no big deal to purchase new ones.

My husband loves the 3mm width and has gotten several compliments.  The style is manly but due to the small width doesn't get in his way.
I wear mine and stack it with other rings to change the style.
