I had some dividend money left over at REI and they had a "20% off a single item" sale that was about to expire, so I bought myself one of these. It's basically an over-engineered minimalist backpacking cookset. Here's a quick run-down of the features:

A 1 liter titanium aluminum cooking pot with integrated high-efficiency heat sink, neoprene insulation, anti-spill cap with drinking hole, and convenient carrying/drinking handle. A small/light fuel cannister and no-priming-needed burner with integrated piezo igniter (no matches!!). All components fit inside the cooking pot. Total weight is 15oz. 22oz. with a full fuel cannister.

Sounds impressive...

My friend Steve showed me his at a recent caving meeting and I was impressed by how compact and light it was. I was skeptical of some of the claims about how efficient it was, how quickly it would boil water, that it would still work pretty well even if it tipped over, that the neoprene cozy wouldn't melt, etc.

Then I read this review which includes some reasonably scientific comparison tests between the Jetboil and other stoves. It demonstrates a remarkable increase in efficiency over other stoves (including the one I have been using for the last few years). They also have two videos - one of the stove continuing to work without spillage while sitting on its side, and the other that follows the entire process from fully-stowed to boiling water with Ramen in it - in under 2.5 minutes.

I'm sold. And between my coupon and dividend, I got it and five fuel cannisters shipped to my door for significantly less than the cost of the stove.
