This stove is excellent under two conditions:

1) A backpacker is willing to sacrifice a few ounces to have a stove with great fuel versatility.

2) A backpacker is willing to sacrifice a little additional pack space for that same fuel versatility.

In my case this was a sacrifice I was easily willing to make (a few additional ounces and a couple of cubic inches of space).It will be slightly larger and heavier than the backpacking stoves that screw directly onto the butane/propane can (Brunton's version is called "Bruntane"), however in some cases that's an advantage.This stove has it's own "feet" and sits relatively low.Those which screw onto fuel canisters sit higher and can be less stable when using small diameter fuel canisters.In fact, some manufacturers sell a bracket that fits under the fuel canister for those types of top-heavy arrangements.

Maintenance is relatively quick and easy, and the Brunton refurb kits (sold here and elsewhere) include enough parts to virtually rebuild the stove.

The hardest part to learn on this stove is how to get it going using liquid fuels without creating a lot of smoke and soot during warm-up (using butane/propane requires no warm-up period because the fuel is already arriving at the burner as vapor).When using fuels like gasoline, kerosene, and diesel, the stove has a small fiberglass disc that sits at the bottom of the orange cylinder on the stove.This is designed to absorb the liquid fuel so it can burn (pretty much like a wick) and heat the fuel in the burner area and line to vaporize and pressurize it.You'll want to get some fuel on the disc but soaking it is not necessary.If it starts to run out of burnable fuel, open the valve to let some more liquid fuel onto the disc until it's hot enough to vaporize and operate properly.The design is really pretty ingenious.

For short trips, I carry a small bruntane can.For longer trips, liquid fuel in a .5 or 1L canister will provide for a LOT of use.I've tested it with white gas, kerosene, and diesel.From my experience, I'll avoid diesel unless there are no other options as the burn is lower temperature and dirtier.White gas lights quickly, but I prefer kerosene (despite being a little harder to get going when cold).The kerosene burns clean and very hot and the vapors from kerosene aren't as explosive as those from gasoline.If you have an accidental spill with liquid fuel, kerosene is going to be more forgiving than gasoline around open flame.
