This ring is very comfortable.  I like the 6mm width that this is better than the other thicker 8mm designs - it is much more comfortable on my finger.  I ordered a 1/2 size smaller than I normally wear because of all of the great reviews here on Amazon, and it fits very well.
These definitely run large, so I would advise you to also order it a 1/2 size smaller than you need.
For the price, you can't go wrong.
