Love this kettle.
My impressions after using it for a while now:
 It's wider, squat profile is really well suited for the type of home-made cat food can stoves I use most. The flame throws perfectly on the bottom and does not waste fuel at all. (if you're wasting fuel with a pot/stove setup, more than likely you need to switch it up).
 It fits inside my modified Ikea pot stand/wood stove holder like it was made to do so.
 Fits everything in my cook kit inside.
 As far as measuring goes, and it not having measurement lines: really? How often do we use our kits, and how many times would I need too see where one or two cups fill the cookpot to? We remember pin numbers, license numbers, passwords...but we can't remember a simple visual? Take your Titan kettle to the kitchen right now, measure a cup of water, pour it in, burn the approximate fill line to memory. And if your backcountry recipes are THAT complex, then I'm impressed. Emeril meets Survivorman. Ok, rant over. I just don't see how you can knock a point off a rating for that. Learn yourself sumthin' goodly on where the fill lines are. It's not brain surgery.
 Seconds as a cup really well. It's basically just a big cup anyways.
Downsides: haven't found any yet. Not really looking. It does what I want so I can do what I want while camping.
