I was nervous about the quality of the ring since it's so cheap but I was very surprised!

-Comfort fit is spot on to my gold 14K comfort fit- cannot tell the difference between the two
-Weight: This is a heavy ring- which is nice for me- I like the heft of it.  If you want a feather weight- this is not for you
-Size:  9 is true to fit- nothing off on the size as well as it's exactly the same 6mm size as my 14K ring.
-Color:  Perfect (for me). What you see in the picture is what you get- they did a good job representing the product.  I won't scare any one off  to say it's a "dark silver" because it doesn't look dark even indoors.  I was worried about that through all the reviews and different forums that discuss alternative metals as wedding bands.
Durability:  So far so good.  I can't see a scratch on it but I do work in an office - the most I do is slam the paper drawers on the copy machines.  But through normal wear like that for the past 30 days, not a scratch on it.
-Plus, my ring came in a little velvet bag- nice touch.
-Price- this was a little more than some of the others on Amazon and the shipping was fast and issue free.  I ordered two others to compare (a 7mm and an 8mm) from different vendors at $20 apiece and 6 weeks later from placing the order- neither ever showed up.  That would have really upset me if I hadn't already had this one and if they cost a lot more (not that $20 is something I'd throw on the ground and walk away from).  Point is, this seller is reliable!

I should get another one in a 9.5 for when the day comes that I put weight on and no longer can wear a 9!

I must say, if you are on the fence with this purchase, I give it an overwhelming solid recommendation and say "Just do it, you won't be disappointed."
