Ok, I have to say, I am replacing my wedding band which broke. I wanted to go with something a little thinner (from a 6mm) just because I like the way it looked. Since I got it, I am trying to get used to it being so thin. My wife says it looks good and doesnt look "dainty", so I guess I have to trust her :)

The ring is true to size and has a titanium stamp on the inside. The metal is a true titanium gray, which I like, esecially in the thinner 4mm band. I think it looks pretty cool!

Durability-wise, the titanium should not have any problem lasting a lifetime... unles i gain alot of weight, in which case I will have to get another one because it cannot be resized. I have been wearing this for about 18 hours now, and yes, there are some wear scratches on it. This metal, like gold, silver, platinum, steel, etc. will get scratches and wear marks on them. If you want to delay the inevitable, get tungsten carbide. It will eventually show some minor scratches (mine did after a year or so) but will stay like polished chrome for longer... But you are sacraficing the fact that it is brittle. (my tungsten ring cracked on me when I dropped it on the sidewalk)Titanium is strong and will not be as brittle. With the ring being only 4mm, scratches and blemishes are not very apparent at all. You would have to be pretty close to see them.

Also, please do not bleive the hype about it not being able to be cut off in an emergency. This is BS. Check snopes: [...]. I personally work in a hospital, and if we cant get it off with a jewlers saw, we will be getting a dremil from our engineering department. We gotcha covered! ;)
