I have the backcountry boiler which is real is similar to the kettle. I've only had it about a month and so far have only taken it on a couple of day hikes. But initial impressions is it works great actually just takes a hand full of sticks to get a boil and boils water fairly fast. I love the weight, mine weighs in at 8 ounces on my scale.
They do look pretty neat but looks like they weigh 2.6 lbs, bit heavy for backpacking.
What is the weight of your current setup? (ie, stove, pot, fuel for 7 days)
I like the dedicated external long pocket. I have one ordered and now I have a use for it . Stove and food perfect.
