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.
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.
