You can't beat the price, that's for sure.
I'm a little hesitant to depend on one for a big trip, though. Getting the time off, coordinating with friends, getting the permits -- and to risk screwing it up over an $8.00 stove? A Gigapower costs $40.00 at REI and will last a life time of typical use (yes I know the threads can wear out with heavy use, but for most of us, it would be years and years before that happens if at all). Seems like a smart investment to me.
Also, if the weather's bad and you're forced to cook in your shelter, what is the CO output? I doubt somehow that an $8.00 stove had a lot of R&D put into it.
And lastly, what about efficiency? The #1 thing I try to avoid is bringing a second canister (or a larger canister). If this thing is as fast as the Section Hiker review reports, then it's burning through a lot of fuel. If you burn through more fuel, then you might have to carry that second canister or a larger canister. If one were trying to reduce carry weight and bulk, that's not the way to go in my opinion.
On the other hand, for short fair weather local trips, why not?
