Familiarity: I've put it through the wringer
Extremely lightweight and effective. I have the 1.7L version, and I'm highly impressed with the effeciency of the heat transfer. It's not a sales gimmick. It makes a big difference. With both my Primus Express canister stove and my MSR Whisperlite Int'l I am able to bring 1L of water to a rolling boil in around 2 min. 30 seconds. That's pretty dang good!
Super lighweight, but like most UL things you have to treat them gently. The very thin aluminum of this pot will bend fairly easily (not warp from the heat, just bend under too much pressure). Sometimes I take it out of my pack and have to slightly reshape it a bit by hand. Not a big deal. It seems durable enough for the weight.
I have a love/hate relationship with the titanium non-stick coating. It WORKS very well. I've never had to deal with any stuck on food. Even dried on, burnt pasta flakes right off with no hassle. So in regard to effectiveness, Primus nailed it by using titanium instead of teflon. HOWEVER, I don't know anyone who doesn't store their stove, fuel, and cooking utensiles in their pot. Naturally. So if you do, just know that the non-stick coating does scratch off with any friction against metal objects (stove, spork, etc). I have to be very mindful of how I store things in my pot, and I even bend my wind screen into the bottom of the pot to protect the coating. Not a big deal.
Overall, a very effective, lightweight, high tech pot. Two thumbs up!
