Now, as for the "fiddle factor," I'll have to time myself with it. Setting up the windscreen isn't *that* bad. You just pull the cables tight and wind the excess cable around the little davit. You then have to attach the heat reflector and mount the stove on to the top of the windscreen. It is a bit of fiddle, I will grant you that. Horrible? Hmm. Well, I've used a lot of white gas stoves where you have to pump and prime, so this doesn't stymie me, but if you're used to a typical upright canister stove where you just screw it on top of a canister and pop the piezo, then yes this is going to seem like a lot of fiddling around.
One nice aspect of this stove is that they really did a good job of making it compact for what it is. Everything folds up and packs up pretty small. Not as small as a, say a Snow Peak Gigapower (to compare it to the classic of the Snow Peak line of stoves), but not bad for what it is.
