I have had my Vector can for 3 years. I have fired approx 5k since last cleaning with no ill effects. I have taken it apart during the 5k to make sure it wasn't too full of carbon where it would not come apart when I finally decide to clean it. It is a little heavier than most cans (all steel) but it does not throw the gun off balance. Overall I really like my Vector can, Excellent quality and customer service (if you ever need it, I have not).
The can is VERY quiet. Shot it side by side with HK MP5SD and it actually sounded quieter to all who were there. Of course we had no metering devices to measure actual sound.

I did trade for one and it is in transfer right now. The dealer let me test it and it was suprisingly quiet. With subsonic ammo the loudest sound was the bolt closing.
