Sure. I am a new customer, so just know that I don't have previous experience with their cans, but went with the Diamond S quiet for:
+ Their reputation, I haven't bought from them before, but a person that I trust on these matters says they are quality builds.
+ I'm a fan of titanium, it's strength to weight is unmatched, and it looks cool as hell after it's been heated! And you save 13 lbs (and apparently gain 3.5 HP)
+ It is not obnoxiously loud and the sound is great, as Chadly mentioned, it definitely has a throatier pitch to the sound
Conversely:
- They are definitely expensive, Titanium is expensive and is tricky (and potentially dangerous) to weld. If there is a more expensive can on the market, I haven't seen it.
There was a slight hiccup on my order as well, but that was due to them building a new website at the time. Everything worked out and my can showed up like a week after they started shipping, so all is well there.
That was my thought process, the pros outdid the price point and holding it in your hand you can tell the quality of it (and the lightness!) Hope that helps. I'll try and get a sound video in the next couple days with a couple braaps as requested.
